Two of my characters got locked in two days.
In both cases I was travelling around Vvardenfell on top of my mount (probably sprinting), when suddenly I got disconnected. I got some kind of error popup, but unfortunately in both cases it was too quick to read.
The issue happened at two different locations of Vvardenfell.
Both characters in question are now locked and I get error 326 when trying to log back in on them.
I have submitted tickets already, but this is starting to feel like a repeatable bug. I am not sure whether the issue is with Vvardenfell or mounts, or the combination of both.
