What went wrong in what capacity?
wrt to NuclearRebalance, the issue was that Bilka was on vacation for a few weeks (I didn't learn that until he'd been back for ~ a week) and .18 contained an updated Prototype/Generator and new Prototype/BurnerGenerator. I switched NuclearRebalance over from using Generator to using BurnerGenerator, but I could only do that once Bilka got back from vacation and put the changes on the wiki.
wrt to this mod, I didn't even look at updating it for .18. I deprecated it before the .18 launch by several months iirc because I saw that you had updated your copy of the mod to .18. I never had any desire to compete with original mod owners (save one incident with one extreme jerk of a mod owner -- not you, if that wasn't obvious) and so when I see the mods I '[continue]' are updated for the current patch level I deprecate my '[continued]' versions to (hopefully) push people back to the originals.
One thing you'll probably need to change is the icons. They added new icon art and even if you just tint existing icons you'll need to specify the new sizes for all the icons or else things will look weird. There's also a (new?) property called mipmaps (iirc) and it helps pick which of the 4 icon sizes in the .png you want to use. I think. I think that's what it does. I'm not actually sure.
