Title: convoy does not pick up cargo correctly
Post by: Ranran on July 04, 2020, 09:41:45 AM
Currently there are weird decisions on convoy loading cargo.

Explanation:
There was a mirror scheduled line like A - B - C.
There was a lot of cargo going to B at C.
I sent to C an extra convoy. But the convoy did not pick up any cargo. But there is no competitive route there.

I have seen this symptom many times.

I found a solution today. Check reverse route and run the same schedule again.
I think this strange check could also be related to the convoy being teleported to the depot.

Thank you for this. Are you able to upload a reliable reproduction case so that I can look into this further?

I did a similar operation in the same dock with the server save I got, but it wasn't reproducible anymore. Perhaps by doing it once, the symptom may have gone away. Therefore another case has to be sought....

For reference:
There were nearly 1000 mails from Anningdale Island to the [W2] Glyerdale delta Mail Center, so I added a ship for that line. But it didn't pick up any mail at the dock. I checked the reverse route, and opened the schedule and docked at the dock again then it picked it up.
I hadn't found a solution so far, so I always gave up after seeing this phenomenon. (´・ω・`)

I have successfully obtained a save that can confirm that. It is a big saved game of the server.

(Posting was delayed, but the save was a few weeks ago)
There is a bi-directional ship anchored on the same line at the port, but one is not trying to load anything. However, there is a lot of luggage to be loaded on the ship at the port, and more cargoes to be loaded on it arrive by horse carriage.
I found this by accident, not by adding new ones or changing the schedule.


A similar weird symptom is that convoys that depart later may be loaded during scheduled convoys.
