ok, a silly mod, but wanted to share it because it helped me.
When I started using Bobs, I lost uranium (might be something I was doing, but I never figured it out), but gained thorium.. which had no use as of today (according to the bobs posts). This just allows you to convert 1 thorium into 1 uranium, thus allowing you to do nuclear again, which was easier than working out why I didn't have uranium patches any more..
