@Doeboy A previous issue allowed for several fuel instances to be created per player. It's possible the 10k LGF you had added was one of the duplicates which would have been cleaned up during a restart or server crash.
The last update made it to where once that container was empty, it would be deleted to avoid any lost fuel. But if the server crashed, it would have forced them all to delete regardless.
If this issue persists, please let me know, and I apologize for all the recent issues with our quarries!
