Collect Moths Quest STUCK

I've collected all five moths however I cannot find the way out of the dungeon. There is a large purple pillar in the center. Am I suppose to do something to it?

There's a purple wall with a hole to climb through. I don't see any purple pillars in there. There are no purple pillars in the game. Can you use Mark and Recall to get out?

Unfortunately no, I can't use recall. I know what purple wall you are referring to. And there is a brown bush close to it but I can't cut it down.

I'm not sure if that's a bug or not as it's a long time since I made that expansion but I can give you a fix in an update. Will take a bit but hold on. : )

That's a bug. So you can have an item named after you in the coming Chinese expansion if you like. Let me know. Fixing it and sending the files to Elendil so hold on.
