As far as I know, CH has not posted any official errata; although I know from playing the module that there are many issues with it. I've compiled a list (but not completed it yet) but if you search these mesage boards you'll find several clarifications and errata for the module. CG
Thanks asler, I didn't know there weren't any official errata. Though I red somewhere (can't remember where on this board) that there were some errata for the maps.
