Difficulty with Advanced FOW

I'm having difficulties with the advanced fog of war (afow) settings for my pages. When I switch to character the character can see the entire map with afow switched on. When I switch back to GM the entire map is displayed and only outlined by the darkened areas. In addition, the afow allows only snap-to-grid reveal or hide. I've switched back to regular old fow and this fixes the problems, but obviously there are difficulties Roll20 needs to be aware of with afow.

Hi, Greg!  Are you having these issues on the Dev server, or on live? 

Live, 'm petty sure. It's while I'm in my games.

I think I resolved this. FOW and AFOW cannot be used together. I finally figured out Dynamic Lighting and am shifting to that, but there are a couple huge problems there too (Skeletons with darkvision being seen through the walls (and yes, they're sealed) and torches that can be spotted through the walls blocks ahead).
