DrunkenDonkey:Wotlk beta user here too, will carbonite require some info from us, i.e. I have not started leveling yet, can hold till carbonite is in state it can gather quest data from wotlk I can report back?
All startup Lua errors have been fixed, validation skipped if WotLK beta server detected and the map "M" key fixed. Everything seems to be working normally.
In order to collect quest data, we need to add the new zones to our map tables and test it. This should be done in a few days and will be in the next version. All beta changes have been and should continue to be backwards compatible with the current version of the game, so there should be no need for a separate beta version of Carbonite.
