The server just stops after not responding for a long time. I have no idea what causes this issue, and looking through the stack trace I don't see it having to do with a plugin.

Seems to have something to do with villagers? Again not quite sure.

Here's the trace: https://pastebin.com/SPRQUV9Y

I know this is an incredibly vague bug report, but it's vague because I don't know why it's doing what it's doing. If you need anything else please let me know, I'll be happy to help in any way I can.
