Try slapping it on the front or back of the engine, the sides dont take covers. And ofcourse use Extenders if you need to use the sides for something else.
So the tag will block the KU output or EU input unless you use a universal extender and apply the tag to that instead? Odd.. I forgot you could already use the screwdriver to select the exact output power of the engines before you added the tags to the motors.
I had something odd happen today with IC2 crops. I was breeding up more melons and I got an odd looking plant instead. The first time I harvested it, I got raw chicken! The next time I got pink dye. Another plant gave me peanuts. I ate just two peanuts and got the resistance buff. Is that supposed to happen after only two?
