Noted on the difficulty, the levels should be predominantly lower to yours until they plateau but I will check on it. The camping bug is a nice catch. Regarding the taming you would need to spend skill points to learn the skill (which varies in classes) and use it (at least on non adults), there are certain requirements that the books in the class headquarters show. Rage should be super low at low levels but I'll take a look if it is indeed not updating. Btw which skill had the NaN problem?
