As far as I know, SA-MP exception crashes come with an address.
In this topic, we're going to talk and get rid of the 0x007F0C37 exception crash, responsible to appear when invalid modifications are applied to a vehicle and generally a modded one. (Example: Applying a spoiler to a NRG)
Since many car mods don't come with valid modifications, this exception is usually about to come. It appears mostly in multiplayer responsible of many players tuning cars that they haven't modded. So for you out there that have modded cars and experience the exception, this is a heads up for you!
I have found the best solution. I always backup my gta3.img or setup files for mods or even the mods themselves. If you don't, then you'll have to find them again. According to the error, it appears only when invalid modifications are applied, so... you can find a car to replace that doesn't include paintjob, bumper, spoiler and hood modifications. There are a few of them and if you aren't sure you can check this site:
http://gta.wikia.com/Vehicles_in_GTA_San_Andreasfor all the vehicles in-game.
It's that simple, install your vehicle mods replacing cars that do not include the mentioned modifications and all you need is to find these cars.
Enjoy and don't forget... happy modding!
