yup..
I also ran into this issue with MC v1.20.1
Minecraft says

Incompatible mod set!
net.fabricmc.loader.impl.FormattedException: Mod resolution encountered an incompatible mod set!
A potential solution has been determined:
- Replace mod 'Clumps' (clumps) 11.0.0.1 with any version that is compatible with:
- minecraft 1.20.1
Unmet dependency listing:
- Mod 'Clumps' (clumps) 11.0.0.1 requires version 1.20 of 'Minecraft' (minecraft),
- but only the wrong version is present: 1.20.1!

thx for a great mod.

Any updates? A few of us would love to this again on our private server for 1.20.1
