When you are spawning in the tanks with limited fuel it will create files in your server profilefolder\Wilmas\Logging called Wilmas_AviationFuelTankSpawner_Config_Entry_0.log (the number at the end changes depending on how many entries you have so if you spawn 2 tanks you will have Wilmas_AviationFuelTankSpawner_Config_Entry_0.log and Wilmas_AviationFuelTankSpawner_Config_Entry_1.log.) this file is so that it knows it has spawned the tank and not to spawn any more. the file contains the type of tank and its location.

If you change the position of the tank in the config it will automatically change the contents of these files and spawn the new one (it will not delete the old tank from the server so if you get it in the wrong place and change the position in the config you must delete the tank with admin tools)

if you want to repawn the tanks without changing the position (if for whatever reason they despawn they need to be in your types as they have a lifetime) you must delete these files and then on the next server start it will spawn them again. if you edit the contents of these log files it will also respawn the tanks and duplicate them so dont edit them.

Eventually i want to make it so it checks for the tanks on the map rather than rely on a file system but this was the best way i knew to do it at the moment.
