Refund on Crash/kill on minicopter dont work

Hi guys, i added to minicopter:

},
"Amount Of Fuel To Spawn": 0,
"Refund Fuel On Kill": true,
"Refund Fuel On Crash": true,
"Refund Inventory On Kill": true,
"Refund Inventory On Crash": true
},
but seems not to work... i only get Lowgrade for refund but not the items...
Maybe items can drop on crash in a bag or something?

What do you mean "i" added to minicopter?  You changed the code?  It's already there, and it doesn't look quite like you pasted it in.

 },
      "Amount Of Fuel To Spawn": 0,
      "Refund Fuel On Kill": true,
      "Refund Fuel On Crash": true
    },

You can't just add something to the config, that's not on the minicopter. Since the minicopter doesn't have storage by default, you must have a plugin that's placing storage on you mini copter.

If you have the plugin Vehicle Storage https://umod.org/plugins/vehicle-storage then by default,  the items will drop.  If you have only one item, it will be without a white storage wrap, but 2 or more, it will bundle them for you and is very easy to find.
