If a player throws a supply signal, the loot is locked to them ....
- LockSupplySignalCrate: true
- UseTimedUnlock: true
- TimeUntilUnlock (seconds): 300

Also would be cool to add locked crates to whoever started the timer.

It is best to use the FancyDrop plugin to block the air cargo caused by a supply signal.

I do use FancyDrop and I hate it.  It changtes my loot tables of the supply signal airdrops even though I have it set to NOT use custom loot tables.  What's weirder is the custom loot section of the config has nothing it it, so I know it is not using those too.  But the supply signals people throw are definitely giving terrible loot in comparison to vanilla ones (we have a PVE server and a vanilla server so I can compare easily).

I love Fancy drop for the faster drop speed and locking the container.  But everything else about it I hate.  Very bulky plugin for a lot of things I do not need or want.  And the final straw for me is that it is altering the loot somehow.
