Guild Wars 2

I’ve noticed on quite a number of occasions (particularly on my thief) that when i do something that would normally take me out of combat entirely after 30 seconds the combat status hangs on for 5-10 minutes instead. I’ve stealthed run off and still I remain in combat for a very long time before reaching the location I’m traveling to. OR when I’m on a platform WAY above the enemies having the slightest clue where I am I remain in combat status. Is there anything that can be done about this?

Logging out and back in seems to work for me.
This sometimes sticks around for ages even if i since traveled halfway across the instance.

That has happend to me tons of times with my mesmer. It usually happens after I shatter a clone. Very annoying though to say the least.
