Hello, I was playing on a server with friends and when one of them approached a mesa and one of the mod's structures, the server crashed. As soon as he tries to reconnect, the server crashes again.
So I deleted the said structure and the problem was solved. We obviously hid the problem under the rug :p. I hope you can help me.
Im using forge 47.2.14 minecraft 1.20.1.

Here are my latest.log and crash log

Having the same issue. I tried to pregenerate some chunks with another mod and it hit a mesa ruin and crashed.

This might be caused by the Waterlogprocessor that is used. I'll look into that, sorry for the inconvenience!

The Waterlogprocessor is not part of the structure_processors for the Mesa Ruins. There must be an incompatibility with a mod.

@Xalveris I tried to replicate your issue specifically because I could explicitly see you're using the IndustrialVillage Modpack.
I've installed it and tested 3 different Mesa Ruins. Haven't gotten a crash yet.

Testing the Modpack with Mesa Ruins spawning at the bottom of the ocean and still no error :/

I also looked through every nbt file of the structures and there isn't a single one except the mesa ruins containing the {minecraft:wither_skeleton_skull} from your crashes.

The modpack was updated a few days ago which must have fixed whatever incompatibility was causing it then. Thanks for taking the time to investigate the problem!

Alright! Thanks for reporting nonetheless :).
