When I first got SH4,I got sick of the program crashes and I also had to learn the hard way that not all mods play nicely together

.
But now I'm in love with SH4 (running current version of TMO and RSRD)

I've gone around 15 patrols w/o any crashes,
....until last night


I was returing home after an awesome patrol (I sank around 8 ships), and as I hit the return to port button....
The program ceased to function and crashed to desktop







~40k tonnage, down the drain, 2 hours of my evening, down the drain.
The only positive thing, I saved the game early on when I had a convoy alert, but I was unable to find the convoy.

So I get another crack at finding the convoy.
This kinda stuff used to happen all the time, but not as much now with only the 2 mods.
