I'm playing with the latest 1.08 patch and I saw something I hadn't seen playing on previous builds. I was exploring the map when, all of a sudden, quest locations popped up all over. I hadn't researched any adventure techs and had never seen these pop up so frequently before. There were very many notable level 2 through 4s.

I am very close to another civ so I wondered if they had reserached the relevent techs and I could also see what was uncovered, but I never saw this previously, even when close to other civs.

I just wondered if it was a bug or whether I have missed something in the patch notes.
