Screenshots

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?
No.

Which version of DeadlyBossMods are you using?
Latest alpha at the time of fight.

Was it working in a previous version? If yes, which was the last good one?
No idea.

have a theory on what caused fails timer report for frost so fixed that. Grasp doesn't have enough information so it remains unchanged. Grasp isn't a count timer so I can't see which grasp is wrong without previous events in shot
