Sorry boss. Got this:

Perhaps that fix wasn't pushed before build went out?

That'll be because of the way the IC2 API's annotations are listed (hint: incorrectly). Including one class makes us think the whole API's being included. Try downloading the latest industrialcraft-2-2.2.xxx-experimental-api.jar from http://ic2api.player.to:8080/job/IC2_experimental/ and dropping it in your mods folder. It should fix this.

Indeed, it does.

@unpairedbracket Yeah. Noticed it also. Thanks for the hint

@unpairedbracket Great thanks, this seems to have fixed my crashes with Mekanism and Binnie's Mods aswell

It seems that deleting ic2 api folder from redstonearsenal-[1.7.10]1.1.0b4-10.jar works - game is not crashing when that folder is deleted. Thank you, guys

As a temporary measure, that might work. However, I'd really prefer to have Mek in my game without needing an IC2 API that I would never use.

Closing for now.

@vitzli That should work too but I'd be careful about using the RA wrenches - they're the part of the mod that uses that ic2 api class, so they might crash when you try to use them. I've reported the issue to the ic2 tracker, so hopefully we can get this fixed soon.
