After being stuck in The Veil for hours, I decided to look at the forums for solution, and find out that there is this 'Li' guy in the cave to the east, and it has something to do with rocks. So I think I found it, but here is the problem... what exactly to do. When I bind a rock and go near him, he starts to run and hides at some point, or float away with some part of the background with him... and then stop, when I get away and then go back he disapears.
I am inserting a picture, to see what exacty is happening. This is when I'm trying to chase him, at some point he floats through the map (even from above), or he is getting stuck here (it is reproducible, at least for me).

Is it a bug with Li, or is that thing something else?
