So I've worked on game development before, I've came across issues where collision is either missing or extending past a model. It's not at all hard to fix, especially when it's not an entire map or level missing collision or having messed up collision throughout the entire thing.
What's the problem ZOS? In the start of fungal grotto by where the bubble appears, right where the NCP walks to at end of quest, there is few invisible walls. I didn't have a problem with them, they didn't cause me to rip a dungeon. I find it extremely lazy to roll out an update without fixing something like this in your vanilla group dungeons. The walls have caused issues, yesterday a few times the wall caused me to miss heals or aggro. Noticed a cp160 guy got trapped when trying to run to the bubble.
Having a giant invisible wall in the middle of your dungeon isn't excusable lol. Please throw a patch, I'm pretty sure ZOS has already fixed the problem but doesn't want to roll out a new patch just for that.
