Okay. So.
I put all my shiny shiny mods into respective folders in the appropriate MODS folder. I load up Sins, there they are! I activate the three I want to test today, load a new game...
...and it's vanilla Sins. No changes.
I've restarted the game. I've restarted my computer. I've re-extracted the mods. I've tried loading on startup. Nothing seems to work. The only way I can tell the game is interacting with the folder at all is the massive graphical lag I get whenever I'm using the mod loader!
Help?
