SH5 - Crash recovery?

[Atoka220]

Hey
So I picked up SH5 again and let's get straight to the point
I'm writing this the second time cause subsim also timed out after I pressed submit...

SO
I was doing the western british coast region's missions with 72h 200km radius patrols and then headed home along the eastern coast
Came along a 8 ship convoy that I totally annihilated with every single one of my remaining torps and shells. After turning for home base I had no less than 15 ships sunk with a tonnage over 100k
And it was all lost
This piece of...very good game crashed on me as I was only few kms away from Wilhelmshaven

I saved after finishing the last 72h patrol but when I loaded in again, it put me to the last objective, to do the last 72h again...

So is there any kind of dump file, recovery file or anything that I can recover my progress from?
I'm really pissed you know
Or at least tell me that convoy spawns are scripted and this will spawn again at the same time at the same location lol


I googled and also searched here before asking but found no relevant threads about recovery
