For future reference, this issue is caused by the fact that some stats are tracked through SUM and some with AVG aggregation functions.

For future reference, this issue is caused by the smooth function.

Is this limited to the just-loaded paused game state (like Veldthui said) or does it happen after a while? i loaded the save with the current experimental and i can't repro the issue.

Can you also share your in-game audio settings?

Can you share the save? we didn't receive similar reports so it could be something specific to that save.

Fixed in the next experimental with some additional improvements.

Implemented in the next patch.

I tested it and i wasn't able to reproduce the problem, i'll try again with your latest save.
Thanks for providing a detailed report.

Try to click on the bridge, roads and train tracks are controlled from that window.

Correct, it's in the current experimental version.

Fixed in the next patch.

Correct, this happens with long rails due to how the scan\construction timings differ. It's on my TODO list.
Not an error per se but an annoying premature warning.

Fixed in the next patch + station\dock modules input-output indicators.

Can confirm, building a module while the train is loading\unloading triggers the issue.
