Villagers floating around then gone disappeared out to nowhere while they're sleeping

Well, THE UPDATE (MCPE 1.16.100) SUCKED. LOL. All my beloved villagers are keep disappearing while they're sleeping. But actually, it's turn out they are just going invisible and still on their own beds, tho. But it's still sucked, right. Really got me piss confused off. :'((
