callback not workiing

The callback command doesn't seem to work.    Not sure why.  hitting with a hammer works, they spawn when bought, they fly, but /callback vehiclename (/callback minicopter, for instance) doesn't seem to do anything.

Hey! Can you send me your config real quick? Its the VehicleBuy.json file in your oxide/config folder (or carbon/configs if youre on Carbon). Also try typing just /callback without the vehicle name and tell me what pops up in chat. That should show which vehicles can actually be recalled.
