[2.0.14] Circuit condition trigger for interrupts will never fire

[DeutscheGabanna]

What did you do?
I tried to use "circuit condition" trigger for interrupts.

What happened?
The trigger never fires, even if you dumb it down to absolute simplest circuit condition ever.

What did you expect to happen instead? It might be obvious to you, but do it anyway!
I expect these circuit conditions to fire the interrupt:

As you can see on the screenshot, A with signal strength of 1 is equal to A with signal strength of 1. I set this condition up with constant combinators to make it absolutely repeatable.

But the dynamic circuits also fail. For example there: 800 is less than 1000.

Does it happen always, once, or sometimes?
Always.

Things I checked that might be preventing the interrupt from firing
There is a valid path to the pick-up stop. I do not see any alerts telling me otherwise and I can send it to that stop directly if I wanted.
The train is set to Automatic, not Manual mode of driving.
The train stop is configured to "Send to train", and as you can see on the screenshot, the train correctly sees the -800 signal.

What does the rest of the schedule look like? Did it already satisfy the conditions for leaving the current stop?

Post the save please, see 3638.

Sometimes the train does get the signal and sometimes it doesn't.

I think I have a repro for the case where it stops retrieving the signal.

It uses Editor Extensions mod for infinite energy and chests.

When you place the blueprint the two trains go to the right station (Load) get some items and try to go to the bottom left station.
The top one can't go to the bottom station since it has no path and the bottom train can't go to the station since it the station has train limit of 0.
Since both stations on the right have a constant combinator with the yellow signal == 1 connected to it, an interrupt triggers that sends the trains to the top left station (Test-Overload).
So far so good.

1. Now remove the disconnected station from the top train (Test-No-Path).
2. The train stops retrieving the yellow signal and stays in the load station.
3. Now re-place/undo the deletion of the Test-No-Path station.
4. The train still doesn't receive the yellow signal.
5. Open the top train's menu and manually trigger the Test-load interrupt.
6. The train continues going back and forth between Test-Overload and Test-load again.

What is the expected behavior?
Both in step 2 and 4 I expect the yellow signal to be sent to the train and thus move back and forth between Test-load and Test-Overload.
