At first i want to thank you for this great mod-compilation TDW.
It still has some issues to solve like any other mod in the beta stage and I am looking forward to the finished mega-mod of yours. (Can't wait till its done

)
I've browsed this whole topic a few times and I've stumbled over CTD's all over the place - and oddly enough others hardly ever experience them and can enjoy the mod to an extend.
I for myself can not play - or really test this mod to help and locate some errors - , since I either get a CTD during the first tutorial mission or when trying to bypass it (with the saving and reloading hint in bunker of course).
The only regularity of my CTD's is that they always happen near or inside Kiel harbour. Missions and the mods tutorial missions seem to work fine for me.
A real pity that we (or I) can't disable each mod one by one to figure out which part of it causes the CTD. (If you would ask me to place a bet, I would point at the environment mods)
My rig runs a complete CLEAN installation of:
- SH5 and its newest patch - both being correctly installed
- Magnum_Opus_0_0_1
- Magnum_Opus_0_0_1-Patch2 - correctly applied
Tested to use the mega mod without Steelvikings shadows, with and without the nVidia missing lights and all the map varieties. I still get the CTD's near Kiel.
I do hope this helps you a bit to get the CTD issues circumscribed and solved. Once that is done your mod has the possibility to sky-rocket like GWX did in SH3. It simply rocks!
