  been playing for 4 hrs now and i went off to do a quest i came back home and all my stations were missing my inventory was empty toolbar as well and my storage empty crops gone too on the plus side i lost everything but my house is still standing so is my bed and my empty plots but now i cant relearn any stations but all the boxes and storage around map reset however even quest are missing i have tried completely relaunching only way to fix it was to start a new game sucks but it happens loving the game though even with this setback
  
  Edit by Opa: ^ This is a new Issue and doesn´t have to do with older issue, i´ll link it to the new save issue. -> https://bugs.autonomicagame.com/suggestions/701717/critical-save-issue-in-v003alpha23267

  Went to investigate the mysterious signal, and when I came back to my base, the manufacturing station was just gone. It's not in my inventory.. its just gone and now I have to rebuild it.

  I experienced this as well. I had one miner go missing, two wind turbines, and a random segment of my conveyor rail line
  
  In this screenshot you can see where resources made it to on the line, and the empty line to the left where it used to connect which leads to the storage box that was being filled.

  Worth noting that this is happening during gameplay, not related to the save/load feature.

  Did this happen in or after winter?
  There have been mentions that snow destroys machines.
  
  Can you confirm?

  Within a daily cycle, the section of rail shown in the image always disappears.

  Does it despawn completely or just visually? So do you have to place them new every time or are they running but invisible?

  It was not in the winter. But I haven't been able to reproduce the issue either.

  It despawns completely. It's only that part of the rail. It also happened once with another rail on a different construction line, but with this one, it happens once a day. Unfortunately, I haven't been able to determine if it's still due to power loss or other factors that I haven't noticed. I placed a pillar on one of the stones in the background. Perhaps that's an invalid placement location, even though it's not marked as one?

  I've had splitters and storage containters (warehouses) disappear so far. Oh and the crafting bench when I placed a second one at the resource nodes, the one at home went poof.

  Hi all,
  Been messing around trying to get this as repeatable for the devs as possible and think I have something for you.
  Made it into a google page as it's a bit of a task, you can find it here: https://sites.google.com/view/autonomica-disappear-bug/home
  Let me know if you need more info, have added both saves (before and after) following the steps for your convenience.

  addition from my experience with this, it only happened to me when i had all 4 kinds of resources connected to a complete system.
  The rails disappeared next to one of the resource nodes. This happend twice during a run and after replacing the structure to roundabout the resource node this didn´t occur anymore.
  
  I personally do think though that it happens due to a power shortage. Since having a constant electricity flow during the day and the night this didn´t occur to me anymore.
  
  as a comment to Dave´s google site, it isn´t restricted to the marked area, it can occur anywhere on the map.

  I had a large storage disappear after I took an excursion to the other side of the world. It was hooked up to a machine that was cranking out motors at the time, but I had also produced other items that fed into the storage unit so that storage contained a lot of items. It vanished after that little trip and was not there after a save and relog. This happened at the beginning of spring after a very long winter. It was the first time it happened.

  Thanks Opa,
  
  Your response made me head out for another run to verify, this time I started from scratch as vanilla as possible, only focused on building machines, nothing else, as little quests as possible, only slept once in a pre-built bed in the swamp, all mining done manually, no power whatsoever, and as fast as possible to rule out winter / snow being a contributing factor and one machine did still disappear.
  
  I'm yet to see it happen directly in front of me, so I think it may be a distance based thing.
  e.g. move far enough for the game to not render the machine, accidentally freeing up some sort of uuid and allowing another new machine to take the reference of the now unrendered one.
  Have updated the google site to include the new saves (down the bottom of the page). https://sites.google.com/view/autonomica-disappear-bug/home
  
  Dave.

  I had several segments on different rails disappear when they weren't finished and I exited and came back with segments then missing. In the swamp, around the coast and also toward the large mountain in the east of the map.
  
  I just now also had all of my rails disappear when loading in after it struggling to exit last night (I'm assuming due to the amount of items I've placed (enough to run the large full manufacturing plant and to rail slide around the island between rails). This has happened in winter 1987 this time.
  
  Edit: now after trying to rebuild the rails, they aren't working past the first joint - the materials flow to the first join then stop. If I try to rail slide I'm thrown off at the first join too. If I try to break down the rail and rejoin it the post doesn't seem to allow connections anymore.

  Description: I have replicated this for one item (wood wind turbine) two times. I believe this happening for two more items related to bricks, but I did not replicate it because it took a lot of items to create. I built a wind turbine without attaching it. I also built a wind turbine and attached it to an electric pole. I restarted my game, and the turbine was now gone. I continued the game without using turbines and used solar panels only. I upgraded to the point of making bricks. I created a miner, connected to a fabricator to make cement, then connected to another fabricator making bricks, connected to a storage box. All was powered by solar panels connected to an electric pole. After restarting my game, I came back and saw that only the brick factory and the storage box containing the bricks were now completely gone.
  
  Reproduction: see steps above
  
  Reproduction Rate: 2/2
  
  Expected Behavior: I create the item, and it stays in the game.
  
  Build Version: v0.1.0-alpa.20685

  Just got up to placing a miner, as I went back to do the next step, make wires etc, all my previous workstation and machines were gone. Thankfully I was using a pre-existing storage box so my items were still there but it's frustrating to find everything else gone. Currently using the patched black box version that came out today (19/03).

  So, I've been experiencing this twice with the latest build, but under mroe reproducable circumstances:
  
  • Build Version: V0.0.3-alpha.23376
  • Description: Placing machines in certain locations might trigger the machine to get destroyed under certain culling/reload scenarios as you explore the world.
  • Reproduction Steps: in my case building specifically on a big but flat rock on the northern shore of Finomenal Cape triggered it twice, see screenshot. The stairs in the background directly lead to the water fountain for refilling bottles to give some orientation.
  • Reproduction Rate: 2/unknown
  • Expected Behavior: Machines should not be subject to destruction under these circumstances.

  - Version Number 23466
  - First thing I noticed is that I could no longer use the E key to interact with machines (or anything else). I left the game thinking I could clear it out with a restart, and when I returned all the rails connecting my machines were gone and the contents of storage boxes gone. In addition, I no longer had anything in my inventory including money or tools. The machines were still connected to power and working.
  - no screen shots

  • Build Version: v.0.0.3-alpha.23466
  • Description: I built a satellite factory for iron frames and the rails wouldn't work. Building a tiny miner-smelter combo in the bamboo area fixed it for short, but exiting to menu and loading again froze the rails again. Also all rail content was turned invisible or deleted.
  • Reproduction Steps: Build a complex enough/long enough factory and/or rail setup (in my case production of every basic resource and up until rotors at Finomenal Cape, iron frames at Dry River Point, 4 extra fabricators for bioplastic and wood products and a transport/fast travel rail from Finomenal Cape to the Autofarms/Dish and then from there to the iron node at Dry River Point with 3 storages as waypoints.
  • Reproduction Rate: hard to get the rail system running again, so I guess 2/2
  • Expected Behavior: The rail transport should not freeze and hide the content.

  I just had my two Workbenches disappear on me. Monthes ago the lines bringing Loot from A to B vanish sometimes.
  the common denominator I saw is that i built all of the vanished things on the big Terrain Stones lying everywhere.
