Disapperings of items and envoirment

after several hours of playing and making chests, Windows and other things that can be massivly producted they disapear like a rabbit one placed nearby and the first just got sucked up in the middle of nowhere how is this possible i would actually say this a very little bug so long big chests of gold don’t disapear then everthing is ok

Also had a small bug where i got 1 fence in inventory but can never find it to sell it during shopping. Kinda find a way around by trying to place that item on ground and pick it back up or delete it from the world.
