Harmony - Troop Symmetry

Maybe I'm reinventing the wheel, but you can still congratulate me – I solved the problem with the "education" skill for the Barbarian, which caused him to retain all the bonuses even after resetting the skill. I actually had the idea of how to do this a few years ago, but I didn't have time to try it out. I tried it – and it worked! The problem lies not in the Barbarian himself, but in his duplicate "barbarian_learning" education. All I had to do was replace it with a standard education, and the problem disappeared. The only difficulty is with the perks – now the Barbarian has standard perks, not his own, but I've already fixed that. Maybe someone has already done this, but I haven't heard about it, so forgive me if I'm reinventing the wheel).
