There are two bugs that are crucial to get fixed.
1: If you have more than 1 (One) Power shard in your inventory. Like say, 6 of them. And then drag them into a machine(Does not matter what machine), you WILL lose every power shard except one. The machine takes one, and the rest is gone.
2. If you flip your tractor and go out, the tractor will fly far up into the air and end up somewhere else on the map. This happened to me 4 times in a row and had to run from 400 meters to 1200 meters to get the tractor.
