That said, Curse of Doom is indeed a curse and should be appearing as part of the "Curse" debuff-type status. Are other curses correctly displayed?
OK tried it in the battlegrounds:
Curses are shown. I'll try out next ID on Yogg Saron - this time with disabled range filter - perhaps this was the cause.
One thing though - A guild member which uses AGUF raid-frames also didn't see the curses of Yogg Saron. Only Decursive shows these curses. Perhaps it's a problem with German clients? Or because a warlock curse has the same name (Curse of Doom / Fluch der Verdammnis)? Or a library has problems with that curse?
p.s. Deseases, Magic etc are shown correctly at Yogg Saron
