HELP! SH3-GWX3 Saves CTD.

[BigWalleye]

I am playing SH3 with GWX v3.0, and using SH3 Commander. Recently, I have begun experiencing an intermittent problem: after a certain point in a career patrol, any time I try to save the game, reloading results in a CTD. I have tried to isolate the conditions under which this will occur. The only consistent factor is that it usually happens after I have had an encounter with the enemy. It doesn’t have to be warships, it doesn’t have to involve combat – I can run away. But, from some point on in a career patrol, I can not save the game and successfully reload the save.

I am running the following mod load:

I have all h.sie’s and Stiebler’s patches active except Wolfpack Less Contact Reports. I have tried saving more than 50km from land and more than 50km from any contact. Still get CTDs when reloading saves (NOT all the time!).

My machine is an AlienWare M11X, i7@1.70GHz, 8GB, Win7 Home Premium 64bit, nVidia GeForce 540M. I run SH5 on this rig with reduced graphics fidelity. For SH3, I presently have all GPU settings strapped down to app-controlled.

I have just completed a complete, ground-up re-install, in which I restored everything from the original downloaded files. (Stock SH3 is DVD with v1.4.) Anticipated that would fix the problem. Just got a CTD after sinking a small freighter with the deck gun in the Thames estuary on September 3, 1939 and fleeing a patrol craft. I submerged, let the PC go by, then resurfaced and ran out into the North Sea. Saved - reload was a CTD.

Has anybody had this problem? I’ve Googled everything I could think of and not seen a similar problem reported. At this point, I am at a loss. I would hate to have to play every patrol through without stopping!

I would sure appreciate any help!
