Hi, I´ve added some of platypings python wonders to K-Mod. One of this is the Grand Canal. Now in a Pitboss Game we had some OOS (almost every round). The gamestats of all the players are the same but the ones of the pitboss-server are different. I have tested all my python changes in deactivating all and activating one by one. As a result the following code in the GameUtils.py are the reason for the OOS: Code: def cannotConstruct(self,argsList): pCity = argsList eBuilding = argsList bContinue = argsList bTestVisible = argsList bIgnoreCost = argsList iPlayer = pCity.getOwner() pPlayer = gc.getPlayer(iPlayer) pTeam = gc.getTeam(pPlayer.getTeam()) ## Grand Canal Start ## [COLOR="Red"] if eBuilding == gc.getInfoTypeForString("BUILDING_GRAND_CANAL"): if CyMap().getLandPlots() * 100 /CyMap().numPlots() > 75: return True if pCity.isCoastal(10): return True if pCity.plot().isRiver(): return True[/COLOR] ## Platyping Wonders End ## return False Has anyone an idea why the code results in an OOS? Thank you for your help.
