Since patch 4, I can no longer upcast Animate Dead for skeletons or zombies! This is a particular problem for my Necromancer, but it' the same situation with Shadowheart. I have the spell slots available, I have the spell selected. And yet, if I go to select the higher spell slot, it highlights like it is possible, and I can click it, but shunts the selection immediately back to the lowest spell slot possible, and will not let me raise my 4 skeletons or 3 zombies. The interesting thing is, it will let me upcast both types of Ghouls, which I could not do before the patch!

Is this a bug or a feature or both!?
