This is a visual bug, it doesn't really affect anything, but...
After dealing with the mine problems, needing to take care of EVIL RAT in the sewers. I forgot to take care of something in the mines, I have MC, Bastet, and Grace (because I needed to see what was behind the pillar I missed the first time!) What appears to be Val and Mariah show up in a few areas in the mines. Interacting with them does nothing. They aren't blocking anything, just...there. (most recent version, 3405)
