ok so i did fix it. one other program was making this not possibel. in your script it was something like peremiters i forgot what it was called but if you can tell me what you have in your script file i will know the name. What it does is saves viechles anywhere on the map and that was the proble.

@flying_bulletzzz yes i did as soon as i enable mp it crashes. i tryed with menyoo and ent and same resolt.

I even went in to the codes and enabled the 0 to 1 and then the game just crashes on start.

@StreetRatKnight ye i have seen a lot of people are having those problem with no way to solve it.

ok so i downloaded a GTA V single player put a bunch of things up all is good so far. Now i came across the script section for the mods so i decided to get some stuff from there. and that where it started. So i have manyoo, native trainer, and simple installed. and all the other stuff to make the mods to work. so i install safe houses mod (https://www.gta5-mods.com/scripts/safehouse-reloaded-a-expansion-to-spa) load the game through steam hi everything is on the map nice it worked. So i get to the first safe house get to the door and boom fall through the floor. Crap something is off. So i start reasercing finally figured out i need to enable online maps. Great load the game go in to all 3 trainers and crsh on every trainer. I am lost i been messing with this all day and NOTHING. dealiting reinstalling and loading without steam and so on. still crashing when trying to enable it. so now i come here with my head down and ready to give up after this.

I been reading online it seems some other people had these problems and no one ever solved it.
So if anyone can help would be great.
