So when I installed flans mod to my mods I got this error. I have had traincraft for a while but something seems to be conflicting.

Yeah sorry, so what do I fix in the config files then?

I can't walk you through that process because it's somewhat mod-specific.
I am so glad forge in 1.7 added in dynamic block/item ID's, leading to the end of the 'block/item ID conflict'

Yeah, flans mod work fine when I take out traincraft.

Just found a fix, deleted both traincraft and flans mod config files.
