Hi I found a huge bug in the game. I built a huge 3 floor warehouse and make multiple items to store resources in it. The game crashed, and deleted the whole structure and everything in it, it also deleted a couple of my palisade gates and walls I had built around the same time I built the warehouse. Now, when I try and load a game its giving me a long loading screen and no progress in getting into my load game. Only way I can get in is by going into some of my very old load games and work from there. Is there anyway to fix this major issue?
