1. accept hauling contract
2. pick up freight
3. deliver freight to elevator
4. Elevator stalls, cargo is no longer 'contracted' after it eventually completes. Server swap after resulted in no change.

What happened
your new elevator code is broken. It is generating FREE sellable freight and breaking the hauling professional loop.

You did not test what you deployed clearly.

What should have happened
the 'contracted' freight should have disappeared and updated hauling mission completion.

Workaround
there is no work around, it is now non-contracted freight and doesn't even have stolen flag.
