To be fair, the name of the jar is dimdungeons-1.13.4-forge-1.18.1.jar

I have a few compile errors left in my 1.18.2 port. There were some breaking changes in vanilla minecraft to worldgen and tags. I promise the 1.18.2 port is coming soon.

Yes I know :) I searched for code or an issue to indicate this was already seen but didn’t see any. Thank you!!

Apparently by "soon" I meant "later today". I just finished the 1.18.2 port!

I released it hastily after an hour of testing in single player. It's been delayed long enough and no one has reported any serious issues with version 1.14 in 1.18.1 so it's probably fine.
