In some games when you try to evolve as Behemoth, it just spams the evolution animation, before you are able to choose your perks. Because of this, you are unable to evolve at all, making the game almost impossible to win. And if you actually get it past the egg animation, you aren’t able to pick any skills. This is really infuriating, especially when doing good in ranked and losing because you can’t move anymore.
You can also get out of the loop by pressing V again, but the next time you evolve, you get the same problem.
