Here it is

Seems like you don't have the latest Collective version. What is the jar name inside your mods folder (e.g. collective-*) or the collective version inside the mod list?

Ah, from inside the crash log: collective-1.12.2-2.25.jar
Update Collective to the latest version, which should solve the problem. Did you update Nether Portal Spread yourself manually?

Oh okay that fixed it thank you for the fast responses.

I don't recall updating, or is it part of the modpack.

Going to close the issue now, thank you so much.
