I was actually wondering exactly what is this part of code doing exactly, i could find the correspondences of all the HEX part on the web like
http://wowdiff.googlecode.com/svn-hi.../Constants.lua
but the last bit you mentioned, i couldn't find it anywhere… do you know what this is doing ?
i'm gonna try first to see what happens when i set it to FLAG instead of GUID and see if anything happens..
