[2.1.7] Train interrupts not working

[urquelle]

After 2.1 update, all of my train interrupts ceased to work automatically. The interrupt appears to kick in, but the train does not leave the station unless I manually press the "pause" button in locomotive. Instead of pausing however, it forces interrupt to actually work and the train leaves the station. I have included both video showcasing the bug and the save in question.

I believe there is at least one race condition when changing the quality of a train which results in the train being stuck.

One reliable way to reproduce this is to trigger the upgrade while a train is unloading such that it will finish unloading before the bots upgrade the train. When the bots finish upgrading the train, it will be executing the loading interrupt, while staying at the unloading station indefinitely.

Is it even only about interruptions? I have several trains that get stuck like this (see image). There is no limit on the destination station, there is no train blocking the route. It's already kind of going (there is the stop-button). When I press that button, it starts actually going immediately. The train is on WAIT_STATION -state according to the debug info (not visible here).

I did the "whole-base-wide-upgrade" to legendary trains, did you do that as well, or did your trains break without doing anything? I already reported one bug related to that, but also several of my trains got cut in half, leaving the rolling stock behind. I've been unable to replicate that still. viewtopic.php?p=695502

Yes I did that as well. Having manually deconstructed and placed again all my trains seem to have solved the problem.

Yes, I did the whole base upgrade, all my trains were jammed. I spent some time figuring out how to reproduce an issue, and posted it. But I think the problem is bigger than what I've described.
