If the server is extremely laggy and you pick up a vehicle with a wrench, it may be duplicated up to four times (Giving you four vehicles from one)

Fixed in V20.1.0.

If I had to guess, this stems from me not checking if the vehicle has been marked as dead/inactive on the server prior to calling the code to drop an item, leading to the vehicle dropping itself however many times the packet is sent. Will fix.

Should be fixed as of V15.9.1.

So it turns out I put the fix in the wrong packet. Re-opening.

Fixed in 15.10.0.

Apparently UN-fixed in V19.15.7.
