What happens if I open Grand Theft Auto V (the default/standard app from Steam or from my desktop, etc.) with only the LSPD First Response plugin installed in my game's directory? I know that I won't be able to play LSPDFR, but that's really the whole point; I only want to play missions in Singleplayer. I already played the game through Steam for a bit since as I'm typing this, I still haven't installed LSPDFR. So will the game crash, and if not, will my missions save (if I open the game through RPH the next time)?
You could also put in any additional things that you would like me to know in the comments.
P.S. I am a noob to modding and this is my first time ever playing GTA on PC. (I was a PlayStation player.)
