So recently I was "stuck between a rock and a hard place" LITERALLY! So I created a new character and was level 12 I tried to sneak away so I didn't have to engage in a fight... and I got stuck between a rock and a wall. I saw a gap and tried to sneak through it, and that's how I could stuck (tragic I know). I tried everything I could, but I couldn't escape and my screen was violently shaking up and down: I tried quick travelling, queuing up for a flash-point (but it took ages ), resetting my game, logging on and logging off and they didn't work!
But I eventually found something that worked and all you have to do it travel to your stronghold. So this is just a tip for anyone that experiences this just because it's annoying and I hope it helped !!!
