ToME: the Tales of Maj'Eyal

Every time I highlight Relentless Pursuit in my skill bar, it triggers Spin Fate, giving me bonus physical saves, spell saves and mental saves (everything but defense).
My guess is that it happens because the pop-up for Relentless Pursuit needs to check saves to display the exact turn reductions.

I've had the same thing happen when I check out the talents tab on the character information screen.
