Guild Wars 2

I have experienced this on my elemental many times. I will completly loss the ability to move my character (including jumping). To get rid of my only solution is to log out and in (to character select). This happens in combat mostly so i presume it is one of my abilities triggering it. Possibly not ability triggered, it also seems to happen when i am hit with attacks, there is no status debuff and the loss of movement persists until i log out and in.

it is really annoying as i have had to on occasion redo half a story quest because this bug has happened and i have had to log in and out (cancelling quest). It is also happened when i was fighting mobs in a jumping puzzle and when fighting an event veteran abomination.

In most cases this happens due to accidentally pressing the enter-key which will send the focus (and blinking cursor) to the chat window. All following keys pressed are going to the chat window then. By either pressing enter again (and sending whatever you typed to the selected chat channel) or by left-clicking somewhere the game window you can bring back the focus to the game.

That is a completely different issue.
Aside from logging out you should also be able to get out of it using some sort of movement skill(2 on warrior/ranger sword, 2 on mesmer staff, 3 on warrior/guardian/ranger gs, …).

One of the skills Shaman Arderus uses in his second ‘phase’ seems to trigger more often than other skills. It’s an AoE pull.

This sadly (and gladly) is not the problem. This is some sort of combat related glitch.

More infomation: I play a Sylvarri Elementalist, i am mostly using sta kitten and fire attunement so if the bug is caused by one of my abilities that narrows it down. However it may be (thinking back) related to being knocked back, pretty sure i lost movement at least twice this way, once by a risen brute and another time by a veteran undead abomination and i also think once by a nightmare seed turret.
