The problem with the code 1002 error, is that you can roll something really good in the rune temple like a vitality rune, and then the game takes it away from you due to this bug. I get this error 1002 all the time while playing the game normally. And yes, one time I did lose a vitality rune. At least the rune I rolled next was a legendary, but it wasn't a vitality. I definitely see this as a bug, and it should be fixed.
