I've been at this one for a while. I've been trying to figure it out, and look at other peoples' similar problems, but I just can't seem to figure it out. Everything seems to be going fine and them boom, at line 380 it says Railcraft is crashing because it needs forge 220.127.116.116. I installed that particular version, cleared the config files, and I still get it.
I've noticed on line 248 FML is parsing 2 arrays of forge. I don't know the exact check on those arrays, as I'm not a Java expert, and haven't checked.
I've done just about everything I can think of, plus a little more.
When I remove Railcraft it works just fine, but when I have Railcraft in there, it crashes. If I put in an outdated Railcraft it works fine.
If you need anything else, please tell. I am very anxious to get this fixed so I can keep my mods up to date.
