Since the previous Nether update, I and my other realm users have noticed unusual behaviour for despawning and respawning, mainly despawning. Usually, it's mobs despawning either extremely quickly or mobs such as Horses and Villagers (even with nametags and tied) vanishing. Respawning seems a little odd, I've noticed mobs spawning in well lit areas but I'm not sure if I'm just imagining that one, to be honest, but I've noted several incidents of these despawns from my realm's users.
I don't particularly have an idea as to what circumstances causes the despawning, it just seems to happen at random. But before the update we never had this sort of behaviour, rarely it would happen and we would shrug it off as a small error, but we have had this new world for about a month and many mobs have vanished without much reason.
Thank you for your report!
However, this issue is Invalid.
Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
Please note that these issues have all very likely already been reported in the MCPE project. In particular see MCPE-21416, MCPE-58182, and MCPE-302. Also note that general game issues should be reported to the MCPE project unless they are specifically related to realms.
