This bug is definitely infuriating since it tends to happen about 50% of the time or more. I’ve had to bind the /sit emote to a macro just to get unstuck, very inconvenient and annoying but seems to do the trick.
Hoping for a fix because thus far since I started playing Rev when HoT came out, nothing much has gone wrong with the class, others have stated some bugs here and there but nothing this broken, at least for me anyway.
Fingers crossed for a fixed, please Anet ^^
