cured villagers and NAMED horses and tamed horse in general have been despawning when I load up my realm.

cured villagers and NAMED horses and tamed horses in general have been despawning whenever I load up my realm. Like I'll have them once I leave the realm and when I come back they're not there, I'm the only person who's active on the realm and I know even if my friends were active they wouldn't kill the villagers because they have no reason to and wouldn't do that kind of thing anyway. I've already lost 2 horses and 4 villagers because of this. The issue has happened 3 times in total.
