Sudden city growth

[zook2]

A weird thing happened on my new map (game version 12.2 ra31077e). I wondered why my network was slowly going bankrupt. Then I noticed that three game months ago, *all* cities on the map (I didn't check them all, but a dozen chosen at random should be proof enough) suddenly more than doubled in population, while passenger levels slowly dropped to nothing.

That must have happened after I reloaded a savegame because of a crash. Before loading it I remembered to switch on autosave in the config file, but I could swear that's the only thing I changed.

Any idea what went wrong here?

Thank you for the report. I am afraid that I cannot diagnose this from screenshots; are you able to upload a saved game in which this issue can reliably be reproduced?

Here's the only savefile I have, but it's after the problem occurred.

Apart from the sudden growth - is there any reason why city growth leads to decreasing passenger levels?

I have just pushed a fix that caused cities to record the wrong population numbers just after map generation, which was fixed on re-loading. Now, the towns give the correct population numbers straight after map generation, which is consistent with the situation after a save/load cycle.

It is difficult to say whether this was the cause of your problem, but it would be useful to know whether you experience anything like this again after the next nightly build.
