Hello, the game crashes and going back one version fixes the issue (biomemakeover-FORGE-1.20.1-1.10.3.jar)
crash report:
crash-2023-10-05_22.27.30-client.txt
(Neo?)Forge 47.2.1
1.20.1

Hm. I can't recreate this on my end, even in a large mod pack.

Could you post your latest.log file?

sorry, only happens with the latest version of supplementaries for some reason.
latest.log
with supplementaries, artifacts and architectury, there's another crash going so your mod is probably fine?

Missing or unsupported mandatory dependencies: Mod ID: 'moonlight', Requested by: 'supplementaries', Expected range: '[1.20-2.8.45,]', Actual version: '1.20-2.8.44'

Looks like you just need to update moonlight

that version of moonlight didn't exist yet at the time of the issue lol
thanks for your help, it's just weird that going back to previous versions didn't work though :(
