I just found a little bug: In Malutina - East Cliffs, there is a bench. on the cliffs. You can sit on the bench, but if you stand up, you are stuck in the fence before it. I think, simply removing the fence or making the bench unusable would help.
Ah, finally, we can get Seles into something truly inescapable (you can only stand up and sit down again). Must be a bench Hephaistos made for Hera, much more effective than any AC-rope could ever be ;-)
Just don't press quicksave when you try out this bench …
