Hello, I have problem with IC2 2.2.658-exp. not showing right names. Blocks and items from IC2 r named like "ic2.xxx", even when I open any machine there's not EU but again "ic2.xxx". I searched a bit and it seems like problem with MFR 2.8.0RC7-71 (it appeared after I added it, and I must use this version of MFR). But I couldn't find what is solution for that.
Update your IC2. You're 99 builds behind, and that bug was definitely fixed in one of them.
