[1.12] MC Crash, try to identify the cause

[phpr]

It is great that Forge is already updated to 1.12 !

The mod authors also post many updates to get it work with the lastest versions of MC and Forge

I like to have all up to date, but since tools like Curse client do not works on my config, I do all manually  (may be you have some tips for that)

This is a crash report using ~45 mods where MC stops on java.lang.NoClassDefFoundError issue (net/minecraftforge/fml/common/registry/IForgeRegistryEntry).

At first view, I am not able to find whenever it is Forge or a mod (and which one) that generate the issue.

Can someone help ?

Thanks.

Forge recently had a breaking change which causes mods to crash. One of your mods is not updated to a version of Forge after the change.

 

Unfortunately, the crash doesn't say which mod it is, so you'll have to take mods out to see which is the crashing one.

The anwer I fear the most

Ok, I just have to grep the "net/minecraftforge/fml/common/registry/IForgeRegistryEntry" strings on files in all the mods to check the bad/old mods (in this instance : Cyclic, journeymap, Magical Map, modnametooltip, Quark, rftools, VillageName : only 7 of 45).

done after updating/removing mods.
