I found this on reddit from u/GammaMarble so i would like to thank him for spreading the word but this mod is made by -1Para-Hustler here on steam so credits go to him.

Work-around for Old Man and possibly other mods:

Load game with SSPCM mod enabled.

Go to the map and press the "LOAD SSPCM" button as normal.

Wait for the SSPCM loading done message.

Press ESC key to get debug console.

In the "Execute" box, copy this: createDialog "RscDialogCheatMenu";

Press "LOCAL EXEC" button.

Press ESC key to close debug console.

Do whatever you want...

To get the SSPCM menu again, just press ESC and then "LOCAL EXEC".

I hope this helps you out.
