I'm not sure if I'm even meant to be posting this here, but here we go.
so I've got these mods installed.
https://www.gta5-mods.com/misc/euphoria-ragdoll-overhaul-ero
https://www.gta5-mods.com/vehicles/gta-iv-style-handling-mod-for-gta-v

and now those together do not cause a crash/stopped working, however I've tried to use this mod
http://gtaxscripting.blogspot.com.au/2016/01/watchdogs-v-hacks-script-mod-by-julionib.html which is just a Watch Dogs hack mod, i've also installed everything its asked me to use there for it, but it still seems to keep going to "GTA V Has stopped working" after about 1-5 minutes of using the mod. could my other mods be conflicting?
