1. wiring: currently there is no max voltage (i can connect a with a without exploding) also the EU-Reader doesn't work
(i know that this is still in progress)
2. empty booze barrel: can't place it, name is "ic2.item.item.EmptBoozeBarrel" (there's a y missing??)
3.items without uses: there are a lot of items e.g. item cases, plates, dense plates which have no uses
4.some problems with NEI: some recipes are shown wrong
5.replication: i think replication is much to expensive now (you need two full to produce enough for 30 dirt (with scrap!)
will there be patterns for all/most blocks in ic and minecraft?)
6. haz mat suit: can swim in lava/walk thourgh fire without getting any damage
7. quantum suit: if carrying any radioactive item the is instantly out of energy (it tries to remove the radiation debuff)
with night vision enabled you are blind during day (don't know if that's a bug)
8. sound: if found sounds for the drill (and some other things) in the ic directory but they aren't ingame
some more randomness for the machines would be nice
edit: how can i get iridium ore without the pattern?
