I used my boost on a lvl 60 warlock. It says processing.
Then it stops processing after a few seconds. I then try 2 login to it.
Get an error saying process requested please wait.
Then throws me to character creation screen. Which actually creates charcters past the cap limit.
After looking at characters 2 xfer on the bnet website they show up there.
You cannot see them on character list ingame. Maybe useful to some1 or for future proofing.
