So today I went to the AH and bought 6 Sting of the Manticore IOs right? I dropped one of them in one of my slots, then i went to grab the second one to drop into the slot next to it,. Apparently my cursor was hovering slightly over the slot I just stuck the first IO on and the second slot when I let go the button - well it replaced the first IO with the 2nd one. I had to return to the AH and re-purchase the first IO that got overwritten. Fortunately it wasn't ridiculously expensive, but still, that's not cool at all. No warning prompt?? Does my mouse really need an accuracy check when I go to drop enhancements in my power slots? C'mon guys, this needs to be fixed.
