Prestige everytime changing skill tree

[rustic pond]

Why everytime I change my skillset in skilltree I have to prestige to apply the change? This never happened before I reached stage 10k.

This is to prevent people from cheesing the game by going back and forth between damage and gold skill trees to gain power that is not intended for them to have all at once. This is a normal change for all players to experience, and you will never again be able to do it
