Getting stuck in combat?
Reported many times, but it’s not “stuck in combat” bug but “stuck in place” bug. The bug is known by ANet but is a “weird repro”, so no ETA on fixing it as far as I know.
Usually happens after leap/shadowstep skills. The /dance emote usually helps you get unstuck.
There is really such “stuck in combat” bug. I can’t recall when it happens exactly but I have gone through it. For some reason you stay in combat mode even when not fighting and away from any mobs (even the border of the screen gets that red shade as if you are in a fight). For me the only way to get rid of it was killing some mob. Teleporting, changing map or whatever didn’t work. Btw, ironically you can’t even teleport to a WP as it says you can’t travel while in combat.
I’m not sure if this is the same as the teleport bug. If it is then you can use an emote to unstuck yourself. Just type /sit and see if it lets you move again. I know; it sucks but its the best way to prevent yourself from dying.
