Idk if this has been reported, but I played a game as behemoth earlier, and I cancelled an evolve, went to pounce traversal, and got 100% stuck. Its on my latest twitch broadcast at 9:55
I suggest filling this out
and for future reference, it helps to include direct links to a video of the bug in question.
You got a link to your twitch channel? Sounds like a weird bug.
Edit: Also could you report it using the issue reporter as Hillbilly_Deathlord suggested?
