HI guys!

Updated our snapshot server this AM, and set out in survival to look for a new plains biome village. After finding a third potential spot for a new village to render-in, the server crashed.

What I expected to happen was...:
Possibly a new plains village to render in

What actually happened was...:
Crashed the server.

Steps to Reproduce:
At this point, the server is running and I cannot log in to the area where I was exploring. Or rather, I log on for about 10 seconds, and then the server crashes.

Here is the server crash report: https://pastebin.com/NEdLjf1F

(I streamed it this morning, if you're interested in the antics of it all ... on Mixer/momibelle.)
