Hi, thank you for taking the time to answer. I edit the file, add the cheatmenu into mods=, put the file into the right folder. But when i start my server it ends up with erosion :reading c:\Users\Captain_Kiwii\Eomboid\multiplayer\servertest\erosion.ini java.lang.NullPointerException at zombie.erosion.season.ErosionSeason.dayDiff(ErosionSeason.java:432) at zombie.erosion.season.ErosionSeason.setSeasonData(ErosionSeason.java:345) at zombie.erosion.season.ErosionSeason.setDay(ErosionSeason.java:270) at zombie.erosion.ErosionMain.start(ErosionMain.java:523) at zombie.erosion.ErosionMain.<init>(ErosionMain.java:96) at zombie.erosion.ErosionGlobals.Boot(ErosionGlobals.java:27) at zombie.iso.IsoWorld.init(IsoWorld.java:1121) at zombie.network.GameServer.main(GameServer.java:251)server terminated C:\Games\Project Zomboid>PAUSEAppuyez sur une touche pour continuer... So, i can't connect to it, i remove the cheatmenu from the text files but the problem remains, any idea? EDit : after backup i tried to delete map_p.bin / map meta / map_t.bin and erosion.ini... still unable to launche the server =( New server work, so i tried to copy the erosion file from the new to the old one : not working either... please help me, you're my only hope =( As far as your mod is concerned, it work like a charm (new server). But i would really love to get my own server to work again... ( it was working yesterday, this morning i launch it and the power shut down with my pc, after that i had the error you know)
