Demonform bug 11.01.2025

When I use high level spells in demon form it turns off immediately.
But when I use a low level spell it's ok. Yesterday I had a bug with my demon form. I just couldn't press the ability, it was unclickable. I had to remove the ability and learn it again. Today I encountered another bug: I can’t use my spells in the form of a demon.
