Return of Reckoning

Any idea what causes this?

Buffs/debuffs from everyone stack up infinite and never fades, then transfers over to everything I target.

Tracked it down to two addons interfering one i can live without the other one is Buffhead.
Tried clearing/reseting/disabling everything to no avail.

It's started happening about a month ago out of nowhere, no settings or new addons added.

No one?

That has nothing to do with buffhead though, i'm quite sure. It's just one of the downsides with running the regular UI.
I would recommend using Pure to get rid of that.

Have had zero issues up until a month ago, which is why Im quite baffled.
The other addon causing the same issue is CastSequence, which I've only ever used on my WE
(whom has been benched for well over a year).

Suppose I have to try out another UI, kinds sucks since Im one of those who want to utilize as few addons as possible.
