Issue Description

Playing in a pack with a few mods which (may) affect world gen. I came across a village with ~4000 villagers at x218 z1155 Seed "3065272"
It had my fps at zero. I've encountered a couple of spots with 0 fps but this is the first time I've found the cause. I'll be doing some more testing and will update this ticket in due course.

Reproduce Steps

Additional Information

I played with this for about 2 hours. Unfortunately I wasn't able to track it down definitively and with the chunk-creation lag, I'm afraid my patience ran out. My guess though is that it happens when RTG is in the pack in addition to MCA. When they were both in, I would frequently get an error "Last tick took 60s, assuming something has crashed. Shutting down the server."

I would only be able to fix an issue like this if it were local to MCA. Unfortunately it sounds like RTG may be causing this problem in some way.

Closing for now, but if you find anything definitive respond here and it will come to me.
