Due to the weird way steam works. When a DLC is created, it keeps its first original created name. Due to that i have to make a new DLC.

but you can still buy this one until the new one is ready/released. It will unlock Adventures all the same.
This one is just the previous "Witch" class dlc. so it will show up as that.

but like stated in the large update. All previous DLC's unlock the AoA whole bundle.
