I was wrong about the tool modes, they work fine (electric wrench, mining laser), I wasn't able to change the jetpack mode. I still can't, but I think that might be an vanilla bug too (couldn't change it on my vanilla server). It seems like if you hold the mode key down while flying it acts like hover mode -- but it never really switches.
Anyway thats a vanilla bug as far as I can tell so don't worry about it.
== just tested R2, fixed everything I could find. My nuclear reactor is fine, my crazy water power system is fine, forestry machines all work. Now I can finally go play with all the cool EE stuff. Thanks a ton, and if you ever need help testing let me know.
