Sometimes when opening Minecraft, I get an error during the sided_setup phase, during which it usually blames Firma: Civilization. However, just now I got the same error, but it blamed this mod instead.

Here's the crash report: crash1.txt

And here's a link to the issue on FirmaCiv's issue tracker: HyperDashPony/FirmaCiv#57

Wait hang on this is the 1.18 mod nevermind my bad. I'm using the 1.20 fork which doesn't seem to have a github page. Anyway sorry about this
