I am seeing a major discrepancy between the FGU CoS module and the adventure purchased from WoTC. Specifically chaper 3(which is the start of the campaign) is completely differnt, so if you prepare using the WoTC material then try to run in FGU you will have prepared the wrong information. Specifically the Burgonmasters residence map has a ton of stuff that is not mentioned anywhere, so when you bring that map up to run through it, you have details that you did not prepare for. Also there is no map for Mad Mary's residence
