Have you tried removing the handcart? IIRC, you have to completely empty the building to terminate the contract.
Works thanks ;
Glad that worked, although you made a good point in the previous comment - the handcart automatically spawns, so I think you should be able to abandon a contract with the handcart still in its default area!
sorry to say but the handcart trick doesnt works on 26 thirdstreet , tried multiple times
We got this on Github already.
The bug itself was fixed today, but savegames will still be broken.
