I've done some testing on PTR now and I have either failed to reproduce the conditions under which Misery doesn't allow reapplying FFF or they have fixed this.
(done 2 scenarios, one was me applying FFF first -> Misery -> me reapplying. Second: Misery -> FFF -> reapplying)
I was unable to get moonkin to assist me though, I'll try to get one later.
Could anyone try it aswell and back up/disqualify my findings?
i dont think misery ever efected FFF m8 its IFF+FFF where the problem lies?
