Nightdew so far all I know is, that blink and ghostly have a problem and a few warrior spells (the guy didn't mention them specificly :( ). If you could share a version with the problem solved I would help you testing it.
For some reason SpellStatus is not triggering on certain spells. I'm using SpellStatus_SpellCastInstant, SpellStatus_SpellCastCastingFinish and SpellStatus_SpellCastChannelingStart for CDT2 and got some reports, that spells randomly don't show up.
In my case I cast Hemorrhage, Sinister Strike and Ghostly Strike in one macro based on target debuffs. SpellStatus ist triggering SpellStatus_SpellCastInstant for Sinister and Hemo but not for Ghostly (which would be the important spell here).
If I cast Ghostly by clicking the ActionButton it will trigger the event (the odd thing is, that Sinister and Hemo do always trigger it altough they are cast in the exact same way through CastSpellByName).
