This is a quick and dirty update of this mod for WotC, just enough for it to compile and appear to be working correctly (which was still 6-8 hours of work).

I don't have time to support this nor do any thorough testing but what little testing I have done has shown no issues thus far. All skills assign properly and at least First Aid seems to be working correctly. That's about as far as I've gotten in testing.

If you run into problems with the mod I probably won't be able to provide much support here but I can try to update any broken skills found if and when I have the time.
