Hey,
I looked for this bug on the forum but couldn't find anything.
I have a fully charged lappack in my chestplate slot and use the minig laser, but the lappack won't automatically charge the mining laser. If I put in the lappack in the slot WHILE the mining laser is empty, it will fully charge it (without being discharged) but only in that occasion.
Also when I remove the Lappack from my chest slot it is immediatly discharged.
I use IC² 1.90 SMP, Forge 2.0.0.67.
Hope I'm not the only one with that problem...
