Okay, I don't know if I possibly have a conflicting mod here, or if something in IC2 itself is messed up. I figured it would be best to throw it out there in the event someone else has any of these issues, and possibly find a fix.
There's the modloader info. I haven't crashed or anything, but in case it's needed. Anyway, I have noticed that some machines absolutely will not show GUI's when right-clicked, as well as power generators refuse to output any power. I have tried installing on a new Minecraft folder, but to no avail. In addition to this, I have noticed repeated glitches with the wires, ghost wires that exist even though they were removed, and even exploding wires (those were.. entertaining, and can be seen in the first attached photo. Then, I had also noticed a graphical glitch that occurs no matter where I place the reinforced door. This can be seen in the second attached photo. I really have no clue what went wrong here, but I'd appreciate any help to get it straightened out. Please let me know if you need more information about this.
