I played today only v3.46 and some saves from this v3.46 testing. Not saves from previous versions of your scenario.
Also the gameplay is usually at high speed, because it is a long scenario. At lower speed, when a sub is detected or the Ford CSG is attacked.
What I also did at low speed was the rescue, and it worked.
This is the events list in the editor at the end of the scenario (by time), so that you can see what is active and what is not.
1. Final victory should not be repeatable, and is still active after firing 2 times.
2. Detection of the Nakhimov active, when it was detected and sunk. I did not see this message. I reported this before.
3. The rescue events seem to be active. But again I play at high speed, and the 30% of not generating survivors perhaps were the cause.

The stuff noticed today:
Minor. Perhaps the format of this text can be improved?

This is the first victory message when the A. Nakhimov was sunk.
I do not know where these points come from or why are they displayed, by this time I had 6780.
As you see there is a next button activated that is the announcement of the Nakhimov that is sunk.

I continued, when the Yasen-M was sunk, the victory message appeared again.
The points are not correct either, I had 16530. Also the next message button is active for the Yasen-M sunk announcement.

What I would expect is:
1. One message when Nakhimov or Yasen-M is sunk.
2. One message when the second of the above is sunk.
3. Then, the victory message. If possible with some delay, so that the 2 messages are not displayed at the same time.
4. Remove those points in the messages because they are incorrect.
5. I continued till the end, trying to simulate that any of the above was not sunk. No message and points indicating that the crossing of red subs was avoided, this time I could do it
If you need the scoring log or the graphic of v3.46 testing, just tell me.
