I am also having an issue where the icons remain on the screen after cooldown is up.
I have had it numerous times through out today and yesterday. Sad I have had no problem until yesterday, I am not sure what changed, but this isn't a long standing issue.
It hasn't been one specific cooldown or icon, no certain amount of times passes before it occers, it just happens randomly. I however, haven't gotten an error message.
Thanks a lot for the otherwise awesome mod!
EDIT: Wanted to clarify that it's all bars: Spell, Item and Expiriring that have been effected by this.
