I updated to the latest version r78963 and upon loading it up on my druid I get an error saying that SpecialEvents-Aura-2.0 library couldn't be found.
I then went to files.wowace.com and downloaded the same version and found it was missing the specified library so I downloaded a couple and found that r78961 was missing it but r7906 had it so I copied it to the libs directory in Decursive but I still get the same error.
Oddly I don't get this error when i login to my mage.
Edit: It also seems to spew the same error on my priest as well.
Same here on my druid and mage
