[2023] Issues with "living death" ultimate

While transformed into a skeleton after using the living death spell, there are 2 issues. 1: You cannot dive while in the form. ????? 2: If you sign during the ultimate, you lose the ultimate immediately. Admittedly, the 2nd one might not be a bug, but the first one surely is.

Edit: Teleporting to wars retreat removes the darkness incantation buff as well.
