The name I double-used is Candela Faeward. When I realized what I had done, I deleted the reincarnation. However, this seems to have bugged the slot. I went back and deleted the pre-existing character with the same name (it was only level 4, which is why I forgot it even existed), but still no sign of an available reincarnation slot. Help!
