Thanks, yes I already play SH 4, on and off when I need a break from Das Boot. I am keeping that for my US SUBPAC operations though. I have installed Operation Monsun and taken a look at the U-Boats - I don't like the lack of TDC dials in the attack scope and the other night when I was trying mods to change that I broke my US Subs TDC dials and stuff in the attack scope (I'm using the OTC mod so that may be a reason) - I couldn't find a mod that worked properly for adding TDC dials to the U-Boats attack scope without messing up the US Subs.
I've tried again to get TWoS working, because I suddenly had an idea. I went back to the install I've been using with Sober's Mega Mod and I removed all the mods using JSGME, so it should have been back to stock SH 5...
I installed TWoS again, and went back and tried that Tutorial TDC mission again, this time with success - no CTD with my fish in the water (I think the CTD was happening as they hit the ship?). So, no idea why that problem happened (it wasn't just that 1 mission either, I tried the other tutorial mission with the freighter coming from the east and had the same issue), as I followed the same procedure, but apparently it's now working...
The ship did jump fully out of the water as it exploded though.
I'll start a new campaign (again!
) and see how stable it is.
EDIT - I spoke too soon. Was ordered to relocate to Kiel, upon getting near Kiel the game CTD'd on me!!!
