Hi milvipes, lets see if we can get your problem repaired! As tomoose pointed out, all the parts of this MOD do not work properly in 4.13.4. That being said, it WILL run in 4.13, I use parts of it myself!
Your 70% crash is due to the game reading the new lines you added, and being unable to find the mod that you've installed.
Now before when you mentioned your installation, you said:
The whole thing looks like this:
IL 2 Sturmovik 1946 > #SAS > Command_and_Control_v3.031_HSFX702 > jsgmemods >Command_and_Control_v3.031_HSFX702 > Files
This mod is packed in such a way that it should be run from the JSGMEMODS folder, but I've highlighted the IMPORTANT folder in red above. For a simpler install, you should drop this folder ONLY directly into your #SAS folder.
Once that's done, you can try running the game. You said you'd already installed the .ini entries so it should start no problem.
IF problems persist, try again with the version linked below:
https://www.sas1946.com/main/index.php/topic,26654.msg281790.html#msg281790I use this version in my 4.13.4 and it runs fine, though the same rule applies: not all parts will work with 4.13 games.
Best of luck! Let us know how it goes.
