I completely stocked my pickle farm for the first time yesterday 7/8, and began to set up a hemp farm in my base in the bottom left corner of T4 (US)Scourge. I set up 2 pumps, 2 water purifiers, 16 large seed beds, and 6 sprinklers for it. I also set up 3 vending machines in the open door frames that stayed, but the vending machines didn't.
Everything that was built with a building plan and hammer stayed, but it seems that anything that I placed has been rolled back and removed. This includes all pickles (i think 31k pickles) have disappeared from my composters. I checked everything this morning 7/9 and found out.
