Just add the mod to my pack and I am getting a ASM crash.

I can repeat the issue over and over and is only fixed if I remove the mod.

Can't reproduce in any way. try with only AS and Forge?

This is not an ASM crash.

And idk what registry entry causes this as it doesn't happen for me atm. I'll see to it
