So, after some effort, I managed to install some car mods I downloaded from gta4-mods.com . The mods themselves are working perfectly, only problem is that now, car variety has all but disapeared. By car variety I mean the unmodded ones, because when I'm driving through the city, all I see are cars like the one I'm driving (doesn't matter which car I'm driving, they are always like mine) taxi cabs, and 1 or 2 different car types (I.E: I'm driving a Coquette, next to me there are only cabs, police cars, and sometimes Presidentials or some other brand). When the game does show other cars different than mine, they come in batches, like clones, for example, 5 or 6 cavalcades in a row and so on. It's really annoying the hell outta me, you can guess why. If anyone knows a fix, or the cause of this problem, please, do tell me.
I've done a light research about this and can't find any decent awnser, but, seeing as I'm an amateur regarding mods and etcetera, this may be a common glitch with an easy (or not) fix. Also, I don't know if this is the right location to report this kind of problem, so if it isn't, please forgive me.
