Game Mechanics: Some dots don't display a buff icon

[socialist]

The entire standard poison dot line (shm/nec ones) fails to display their icons in the buff bar. You'll get the message when it lands and you'll take the damage, but no icon and (I think) no wear-off message. This occurs with dots from both players and mobs.

I've tried various UIs and spell icon fixes to no avail. Others have the same problem.

Other non-spell poison effects work as they should, including the various snake/spider poisons.
