This screen shot shows several of the problems I am having now...
I was in Twilight Forge with my guild and my PC mysteriously shut down entirely. When I was able to reboot and log back in I could no longer see spell effects. No big deal, as long as my spells were being cast I can deal with not seeing them.
But icons vanished, hp bars became gray blocks when they would normally turn green to indicate talking. The focus orb turned into a large gray square with a white grid pattern in it, and so did the mini-map.
Worst of all, the door to the titan behind the shrine was physically not there anymore! I could not even target it with backspace.
The above screenshot also shows what happened after I got sick of it and teleported back to House D... House D didnt load. I cannot move. The portable hole is the same way and so is every other location in the teleport spell.
What should I do? The launcher doesnt see anything wrong and the options>repair>reset graphics settings route didn't help either.
