Huge numbers of AI subs not sinking anything in 1.07

I've been noticing in this war with GB and the previous one that even though they've got >100 subs they aren't sinking anything.  Originally I was thinking that my ASW crews were just doing a stunningly good job but it just occurred to me that AI subs might have regressed in 1.07.  Or maybe GB is just buying their torpedo detonators from the Americans

You can see in the screenshot GB has 130 subs and didn't sink anything.  This has been going on since the start of the war, and I think it was happening in the last (very short ~8 months) war too (which was also 1.07) - I think their sub count was 80-ish in that one.  I upgraded to 1.07 in the war before that; I didn't notice one way or another if they were sinking anything with their subs (much lower count), but looking back I suspect they might not have been.  Attaching a save file at the start of the battle that was generated after clicking through on the dialogs in case it helps.

1900 start, France, 1.07 (started at 1.05b) VL fleets, manual build of legacy, Admiral, plus hacked aircraft experience to be all positive and <40 when I switched to 1.07.

Thanks for the report & the save game, we will look into this.

I can confirm, no submarines sunk but merchants too in 1.07.

I do not know if it is issue with game started in previous version or not.

On a sidenote, AI sinking entire budget in building 30-50 subs at a time and pretty much neglecting altogether the other aspects of their navy doesn't seem like sane and intended behaviour, either...
