I have a problem. I found this cave all the way in the SE corner, east past the pond and waterfall, and circle up a slope, climb some steps. There's some ruins and off to the right from when you enter there's a small curving path down into a cave.
When I first got there, there was what seemed like an Aardable wall, but Aard didn't work. So I figured my Aard isn't powerful enough yet. Next level up, I improved my Aard and went back. Lo and behold, the wall is no longer there... except it's still there. I can now see freely into the cave/ruin down a drop, but "drop down" doesn't appear, making Geralt walk up against essentially an invisible wall.
Anyone understand what this is? And how to solve it?
