So basically I noticed that after a new fresh reinstall (after having played around with some tweaks on my prev one), the game started to acting weird, such as triggers not working correctly and immediately freezing the whole game when trying to buy something at the Doherty Ammu-nation weapon shop and proceeding to crash to the desktop altogether (under win 10)
This is the save file I used if you want to check it out: http://gtasnp.com/FmzTSN
And these are the modification pack I used for the game:
Now while I have a prev backup save file I can use, I would rather not have to load that one up since i did made some additional progress since then (outside of missions) and i wouldnt feel comfortable having to redo those all over again, unless absolutely necessary.
I literally tried everything I could think of, including reinstalling the steam version altogether and removing older folders, except for the save data one and still nothing. Any help would be greatly appreciated, as Im really running out of ideas...
