Hmm, well I actually did delete my addons folder and re-install all of my updated addons right after the recent patch (twice actually). I will double check the version of X-Perl but it came out after Oct-15 (or whenever the 3.0 patch was). I did notice that it was a bit buggy - sometimes it doesn't show all of the buffs on the player icons and they appear only after I click/unclick one of the settings in the config menu. Maybe there is a conflict somewhere.

I also tied partycastingbars but it didn't work, but I am assuming because I didn't have that other dependency you mentioned.

Thanks for the suggestions!
