[BUG] Ability CD's Trigger but CD Does Not Fire

[Koltik]

I recently started to notice a bug where I will cast a buff, and the CD will trigger but I will not actually get the buff. This happens most often when having macros which group two cool downs together.

For an example, see this video & watch the buffs: https://www.youtube.com/watch?v=eRD-...etailpage#t=50

The time to watch is between 0:50 - 0:52. You will see that both Berserk and Bloodbath are cast & CD's are triggered, but Bloodbath does not actually stick. I have had this happen in reverse as well, where Bloodbath will stick but Berserk will not.

EDIT: Typo in title; should read "[BUG] Ability CD's Trigger but Ability Does Not Fire"
