[NeoForge 1.21.1] Compatibility issues with multiple mods -> NoClassDefFoundError

Ark-EU opened this issue ยท 1 comments

Hello.

I recently commented on the official curseforge mod page about a weird issue I encountered during the creation of my modpack, which has been caused by the weather2 mod and CoroUtil. Here's a followup on my discoveries while debugging. Some mods seem to trigger the error NoClassDefFoundError in combination with weather2. For NeoForge 1.21.1, those are:

Sinytra Connector https://modrinth.com/mod/connector/version/2.0.0-beta.8+1.21.1

Sinytra Connector Extras https://modrinth.com/mod/connector-extras/version/1.12.1+1.21.1

Cool Rain https://modrinth.com/mod/coolrain/version/1.1.0

Sounds https://modrinth.com/mod/sound/version/2.4.11+1.21-neoforge

YetAnotherConfigLib https://modrinth.com/mod/yacl/version/3.6.6+1.21.1-neoforge

M.R.U. https://modrinth.com/mod/mru/version/1.0.17+1.21.1-neoforge

I will upload the crash-log and Runtime-Log as well. I hope those are helpful in fixing some bugs.
