I have reproduced this bug a few times:
My warrior with the trait “Shrug it off!” will get stuck in place in AC after being feared by the Troll if the trait triggers “Shake it off!” right after the warrior starts running away.
After this, I get stuck in place and need to use a movement skill (main hand sword #2, banner dash, shield dash…) in order to unstuck my character.
Easy to reproduce, hope this will get fixed
