cave biomes+tetra seem to cause crashing(?)

[muppetenergy]

hi there,

Been working on a modpack, and went into a new world to fly around and test stuff out.
Server started crashing (and getting stuck trying to save/go offline). I am not super well versed in reading java things, but it looks like tetra is somehow conflicting with yung's caves and failing to place (lighting? items?)
In subsequent trying to log in, it immediately crashes. server starts up okay, but as soon as I start to load in it goes down again.

Here are a couple of the crash logs, hopefully that is helpful
crash-2024-12-11_05.52.14-server.txt
crash-2024-12-11_05.40.38-server.txt

Just gotta add, I absolutely LOVE your mods! they improve the game drastically and the folks on my server and I have had lots of fun with them. so thank you very much for all your work on them, you're very appreciated.

Please let me know if there's other info I can try to provide

thanks again
