I noticed on a lot of my characters that if I use the Focused Azerite Beam, the icon will not go away. It just stays in the prompt as if it wants me to cast it again, but obviously I can't.

Can you try the alpha version 8.2.6-alpha (https://github.com/Sidoine/Ovale/releases/tag/8.2.6-alpha) and report whether this is fixed or not?

I can't seem to get it to work.

I notice from update 2.7.5 to 2.7.6 a endless spam of Moonfire on my Druid Tank. Mybe something with the DOT detection handling is broken.

This bug should be fixed, tell me if it's the case, please

Just tested, I don't see any errors!
