RSD v5.3 starting at a new campaign, NO silentotto, works fine.
RSD v5.3 starting at a new campaign, WITH silentotto, getting a CTD no event viewer log, I did not run debug view. The CTD happens right at the bunker as the guy says "Sure thing, what do you have in mind." I did not push the upgrade or torpedo option yet. This is always the same symptoms with the guy speaking for all CTDs when mentioned below.
I have concluded that I can not use silentotto and RSD v5.3 at the moment. At least for Mare Nostrum and Battle of Mediterranean. At the moment, I do not feel like testing other campaigns with silentotto and RSD v5.3.
I deleted the menu and texture folders as suggested, then used silentotto and RSD v5.3 and got the CTD starting a new campaign.
My last game saved was with the Battle of Mediterranean campaign using mods posted at #292 but removed RSD v5.3. I then enabled Nauticalwolf's Damage and Torpedo_UI(b)_Mod_v1.1 and then RSD v4. I started this game by using silentotto and picked the Mediterranean campaign. Saved, and exited out of the game. I disabled Nauticalwolf's Damage and Torpedo_UI(b)_Mod_v1.1 and then RSD v4, I enabled RSD v5.3.
This time I started a new campaign, but DID Not use silent otto. I started the coastal waters mission fully loaded and at the bunker of Kiel, I then loaded my save from Battle of Mediterranean campaign using mods posted at #292 WITH RSD v5.3. Whola,


it works where I left off at the last save.
