So I managed to make SOD CS work from scratch (my old save files got deleted, had to redownload the game again).
I will put out a guide with links so that everyone can easily start CS if they played this game before and maxed everything out but lost their saves. Or if you would like to skip the base game and start CS with a maxed out save.
Step 1: download SOD Base Game + DLC.
You must be registered to see the links
Step 2: extract the Part 1-6 so that the base game will work.
Step 3:
Put the DLC files into this location.
Step 4: Test if the game works.
Step 5 (Optional): If you want a fully unlocked save file for base game then use this one:
here,this is 1.32version save
That save works even on the latest version.
Put the save File there and you can now start the SOD CS with 100% base game save (I did not fully check the save file but it has all skills unlocked, large amount of money, and all facilities unlocked so far. HAVE Fun and thanks for the people uploading the game and the saves and creating guides and shit.
