I tried playing OceanBlock with my kids. I start the game single player then open to LAN. But only I can modify (break or place blocks) anything on the island. I believe I have narrowed this down to spawn protection. I tried to /OP everyone but apparently that command has been disabled. I believe there is a setting in Server.Prop file but I can't find that anywhere. I am using the Overwolf->FTB launcher. Any help resolving this would be greatly appreciated.
