Game crashes and all tamed animals disappear

So I’ll be with my tamed wolf and cats when all of a sudden the game will crash and they all disappear. Extremely rarely one of them will reappear when I’m somewhere else? Also I keep having my sheep and horses and every other animal disappear randomly even though they are in a fenced in area. This is all extremely frustrating. The game is becoming unplayable because I get sad when these animals I travel far away to get just disappear constantly.
