Automatic chunk resets. This should not happen. If a chunk reset is the only way the game knows how to "fix" something it should just exit there and tell you which chunk the problem is in and give you an external method to reset the chunk if needed.
Spent most of a day putting every item I've gathered/made on the new dw20 pack into an AE system only for the chunk to reset wiping out everything.
