spamming jump to grind on conveyer belts lets you fly

walked up the exit of a storage building while I had a short conveyor belt attached to a splitter that went to a fabricator, started spamming the jump button and I was able to start flying around on the hoverboard. Getting roughly 2x higher than the fabricator, flight was also limited to a small area around conveyer belts and buildings, also stopped flying after you stopped jumping.
