Bug - Not A Bug Ice sculpture confusing arrowed monsters

I arrowed a reanimated bat skeleton and had it show up twice. After the second time, with one fight left, I used an ice sculpture I crafted when fighting it. When I beat it, mafia seemed to remove the window for encountering it. Perhaps fixed by checking the monster intro text to see if it's from the angel/reanimator?

edit: I just miscounted apparently. Nevermind.
