Oh, i didn't know how it works from the technical side, i just thought that it is do-able. What about making it so colonist will gain XP-point when they finish the training rather than gaining XP over time when they are training? This should be much easier to do, as i'm sure that this kind of mechanics already exist in the game. I get that you don't really want to stop anyone from exploiting this kind of "feature" this mod provides us, but i feel like it's some sort of a bug which should be fixed, to "balance" things or sth like that
