I pet my white chicken while I was in the coop and picked it up. When I tried to put it down it got stuck on my character's right arm. I tried to put it down or equip an item but the chicken stayed stuck. I restarted the game and the chicken was no longer there. It isn't even in my journal anymore. My other animals are still there.
I have also had items disappear out of my processors like boards and gems. It's usually after I've restarted the game or there has been an update.
