Spiritus problem

Hello, I have a serious problem with Spiritus. she is less strong today with 4 stars and purple blessing, than yesterday, at 2 stars with yellow blessing. Worse, I removed her from the team and put herback, it doesn't change anything. It's as if she were no longer active. All the players I beat yesterday are all beating me today as I've increased my power a lot. Do you know what's going on?
