Check the IC2 tab, everything is there.
Uhmmmm, no. Most IC2 armour is in the armour tab, canned food and terra wart are in the food tab, chainsaw is in the tools tab, and the reinforced door is in the redstone tab. All these items do NOT appear in the IC2 tab.
Another minor bug: If you use the mining laser in creative mode, it appears as if it stays fully charged, but actually it runs out of energy after excesive use. Charging the laser then in a MFE updates the charge bar correctly. (A lapback gets drained correctly, after it's empty the laser shows the same behaviour.)
