Ok, so I went to do a quest with a blue exclamation mark. The task is to collect all of the lost artifacts. I have two of them but I can't seem to figure out how to get the third one. It's the one where you have to climb up some vines and it looks like it could be a door that has a symbol on it. There is also a bridge behind it that looks like it leads to the other part of that particular temple. Anyone know how to get this one?
