Hi, I have added one of Platypings wonders to my mod. It works fine but in a pitboss game, I´ve the problem that the pitboss doesn´t use the discount. Every Player in the game has the same gamestats only the pitboss differs. I´ve no idea how to fix this. Here is the code: Code: def getBuildingCostMod(self, argsList): iPlayer, iCityID, iBuilding = argsList pPlayer = gc.getPlayer(iPlayer) pCity = pPlayer.getCity(iCityID) pTeam = gc.getTeam(pPlayer.getTeam()) iCostMod = -1 # Any value > 0 will be used Discount = 0 ## Apadana Palace Start ## if pTeam.getBuildingClassCount(gc.getInfoTypeForString("BUILDINGCLASS_APADANA_PALACE")) == 1: obsoleteTech = gc.getBuildingInfo(gc.getInfoTypeForString("BUILDING_APADANA_PALACE")).getObsoleteTech() if gc.getTeam(pPlayer.getTeam()).isHasTech(obsoleteTech) == false or obsoleteTech == -1: capital = pPlayer.getCapitalCity() if capital.getNumActiveBuilding(iBuilding) == 1 and not pCity.isCapital(): return 80 ## Platyping Wonders End ## return iCostMod Thank you very much for your help. EDIT: I´ve tested the code on standard BtS with only this change. There it works fine even in pitboss games. Since I use K-Mod which is based on BUG it seems, that the changes BUG made with the gameUtils are causing my problems. I testes the code in SP and MP DirectIP (without pitboss). Even there it works perfect. Only the pitboss seems to have the problems.
