What steps will reproduce the problem?
1. Delete WTF
2. Load the game with Totemtimer 10.3.8 enabled
3. Get into a raid group

What is the expected output? What do you see instead?
I've recently reinstalled WoW and starting with a clean WTF I've configured Totemtimers. Since then every time I'm in a raid group I get this error. Please note that the "Count" increasing very fast.
