or you could copy the files from advgens into the ic2 jar
That gives me an exception when I start Minecraft.
Also tried to copy the "core"-files into the ic2jar too (and of course removing both files from the mods-folder) = different crash.
But thats "ok" - I need to use a fresh MCjar anyway since I discovered some more "strange" things (that only seem to happen on my MC) in other mods as well.
Guess it was really a bad idea to *not* use the recommended forge-version
BTW (unrelated):
Any way you could make that PlasmaBattery charge/uncharge-able in a MFSU?
Maybe at lower speed (regarding the lower tier of the MFSU) or with a small EU-loss (to compensate for the "unproper usage")?
