I just entered the Pocket Dimension and everything was black. The GUI kept showing, the minimap kept track of the character, even the tooltips for items on the floor show, BUT IT'S ALL BLACK. I could exit the PD, but now I can't see all the crafting junk I've got in there.
If you walk straight down until you hit the theme changer and change the theme it lets you see once again. So at least one of these bugs isn't fatal for the character. All but one of my post Wizardlands characters has failed due to pocket/wizardland bugs. I've not yet managed to get below DL12 before I get a fatal bug.
Oh THAT'S what fixes this bug. The character died shortly after I found my keys (yay random builds on GRPD) but this was hella annoying.
