Zone Transition Failed

[Yank76]

So just about ever other time I try to change zones I get a "zone transition failed" and I get kicked back to main menu. I have already verified my game files and have cleared it with my anti-virus software, I think it might have something to do with auto saving since every other quick save fails but that isn't as much of a problem as the former.

Here is my transition error

Game Version: 1.1.1.5

Anyone know a fix to this?

i've experienced it, in my case, something caused the save folder to be inaccessible by the game to create a save data there.
but the culprit was actually myself, i opened Windows Security Center and activated the "controlled folder access" feature, that made it so nothing can modify anything without my consent, so the game couldn't make any save data in its own save folder. after i turned it back off, the game can save normally.
your case might not be the same but probably still worth checking.
