Comment 30 for bug 536367

Okay, I have investigated this a bit and indeed found an instance where a ware can become abandoned on a flag: a carrier promises a flag to pick up an item from it before starting to move there. The flag takes notice and informs no other carrier that it has pending wares. If the carrier is then released it did not tell the flag that he will never show up -> the item gets abandoned. The reason ripping roads/flags in the vicinity lead sometimes to a fix is that the item might reroute itself and marks itself pending again so that it will not be picked up and carried in the wrong direction.

I conjectured a fix but I am unable to properly test it. It will avoid this chain of events (theoretically) but nothing can be done for games in which the wares are already abandoned. The fix is in r6335. Please everybody, test over the weekend if possible! If the error is indeed gone we can stay with the plan to winter-time freeze on monday.
