Oh..... I see.... So I see where my issue came from. In the how to guide it says to: drag and drop the "AricsExpansion" folder over the one you got from S4P-RalphsModdedAricsMod097.zip and click yes when it prompts you to overwrite. It replaces two files: expansionsetup.gd and expansion.gd.
"Move the folder "AricsExpansion" from RalphsStandaloneAM097.zip to C:\Users\YOURNAME\AppData\Roaming\Strive\mods\"
But if I do exactly that it deletes 22 odd files. Or at least it did for me. However if I go to C:\Users\YOURNAME\AppData\Roaming\Strive\mods\aricsexpansion\scripts\aricsexpansion\ and only replace the three files that are provided with the patch file then all is good. Is that what you intended?
Well there are no more script errors popping up. YAY!
Lastly... I STILL cant choose a head girl. Kinda annoying since that feature goes a long way to keeping slaves happy/obedient.
