[Nuclear reactor complex - as built by an electrical engineer]

Ah, okay. If RP2, IC2 and BC are mostly the same, I wouldn't mind manually replacing some blocks. It's the whitescreen instead of just removing all the incompatible blocks that's the problem. :/

I saw a Tekkit -> Technic MIDAS list once, I suppose I could just run that backwards (if I can find it again...)

I've been trying to convert this world to Tekkit (for use on my server), but it whitescreens every time. I know the wireless redstone mod is completely different, so I tried breaking all the transmitters and receivers, but it still whitescreens. I've also tried making a schematic of it and pasting that into a working world (both with and without wireless). Still no luck.

I managed to get all my worlds from vanilla into Tekkit without too many problems (had to break all railcraft blocks and replace once in Tekkit), so I don't know what the problem is. Is it this world, or Technic->Tekkit conversion?
