The PS4 Realm I'm in with some friends has an issue of disconnecting whenever we are close to, as in load the chunks with, the villager farm that was created. I've seen similar issues where realms disconnect when loading in a certain chunk so it could be that. The realm is named NinetyAsp195, the same as the name of the creator of the realm. And the bug began about the same time that a raid was accidentally started in the same area as the villager farm and we had to reload a backup before the raid to solve the problem. Since then the villager farm was accessible for a while then started disconnecting again.
