Yes, that is from the save game I uploaded in the suggestions thread.
I think I phrased that a little inaccurate. What I meant is the "Contract First Source Location", that only works for the first contract in the list.
Do I understand you correctly, in that the Contract First Source Location is binding for ALL contracts, not just the one you set it on?
Since I usually had more than enough capacity in one location, I wanted to use it to assign the contracts to one location so that I could better plan my production. Selecting it for each contract doesn't work, since only the setting for the first contract in the list is remembered, the others wont change and they keep showing "Any city".
From the sales behaviour, that seems the case, since I couldn't reliably figure out where the contracts supply was "missing" from normal sales.
OT Edit: While on the subject of bug reports, I just noticed my forum rank is "Pirvate". I wonder if that's intended.
