The wall jumping spots are kind of annoying or upsetting if you have no idea how to get up them.
There are few key spots if blocked off with invisible walls would prevent people from getting out of bounds, unless they position hack.
What I find more disturbing are 2 other bugs.
There is an out of bounds spot that once reached the villager can then drop out of range of ghosts and if followed, by the ghost, the ghost is still unable to stop the villager as you get stuck perma falling and cannot use any skills.
The second I've seen was a villager using a Mesmer portal. They somehow must have obtained access to their class skills, I'm not even sure how that's possible.
