I was playing survival on peaceful difficulty (1.17.41)when I noticed my armour stand disappeared. Thought it was a one time thing and ignored it. Fast forward to today, I now have a donkey and pig saddled and tied to fence posts, as well as two parrots and a new armour stand, but after a long time away from my base they were gone.

not super tech savvy so I can’t provide much more than this, if it happens again I’ll screenshot and update the tracker.

Hope this helps!
