Does anyone know if there are specific steps to take in order to properly upgrade the server? The way that I just tried still gave me a bunch of spam and even reset several of my chunks. My base is completely gone.

As @James_Elliott said, it has been reported in vanilla minecraft servers. The sixth comment on this bug report was by me for that very thing. Would providing my entire server folder help speed up the patching process?

I really wish Mojang would fix this. I can't run my server because it just crashes when I near certain villages.

@Karim_Rivera, when optimizing the world in single player mode, did you use the "Erase Cached Data" feature? Also that was to 1.16 and not 1.16.1 correct?

I have just updated my 1.15.2 server to 1.16.1 and am having the same issue. I was watching the terminal output and noticed that as stated previously the server beings to throw errors every time a player nears a village or crop farm. Thankfully I have many backups. I'm curious, would using the "Optimize World" feature of Java Minecraft be a way to stop this problem? I am going to test it out and will report my findings here.

EDIT: Errors still occur even after using the "Optimize World" feature with "Erase Cached Data" enabled. See "Error.txt" for output and seed information.
