found and mushed. Dare I ask why you were trying to power a wooden transport pipe?
Not quite sure what you mean... What am I supposed to power? I need to pump out items from IC2 machines and other stuff.
ps To reproduce the bug you can try a lever to activate the engine. Just switch it on/off quickly.
pps There is another bug - it seems, that engines limit an IC2-energy packet size.
To reproduce: put induction furnance and 10-12 small engines to 1 common wire (I took fiberglass). Engines must be not activated. Power source may be any (MFS-T2-T1 in my case). Then run a furnance and measure power on it. There are 12 engines on screenshots, and only 8 eu/t to furnance (must be 16), and only 8 taked from MFS, so the engines don't consume any eu.
img 1, power to furnance
img 2, state of the furnance, it shows the furnance don't have enough energy
img3, power taked from MFS, measurement is performed on fiberglass under crosshair
