I encountered a new bug in Cyrodiil yesterday which occurred twice. In both cases I was riding hell bent for leather to defend a back keep from a PvDoor group, and when I got close to the keep I suddenly stopped dead in my tracks still mounted. I was able to dismount and bash but nothing else. I coiuldn't move, use skills, remount or even hit ESC to open the game menu for probably 30 seconds, after which everything returned to normal. Plenty of other players rode past me seemingly unaffected and zone chat seemed normal so it wasn't a server-wide issue.
I wasn't grouped and I run zero addons so these can't be the cause.
Has anyone else experienced this and have you found a fix other than waiting it out?
