Trying to build an iron farm, and villagers and zombies keep disappearing at random. I catch them and put them in a fully walled area and they just vanish. I've also had issues with monsters and animals freezing. In my farm sometimes I shear sheep and some sheep freeze and cannot be sheared. Sometimes when moving animals while using leads they freeze in place and the lead gets infinitely longer without snapping. This has also happened when trying to kill monsters. When playing with my friend on split screen we can sometimes see the disappeared villager or zombie on the other screen while not see him on mine. Issue fixes when closing and reopening the game but that takes a lot of effort for something that happens after a short period of time. Note: I am playing offline split screen on a ps4.
