No I don't use a pirated version of GTA V. I have the Steam Version.
Recently I Installed the RageEuphoria Modification by downloading the 1.3.1 .OIV file and using OpenIV to install the file. It all installed correctly and I started my game. Everything goes fine, the ragdoll physics work but after a while during physical interaction the game will suddenly crash, so there isn't really a trigger apart from the euphoria physics just being used.
I could run five people over with a car for example but it will be fine, though I might run one over and the game will suddenly crash.
I only use NativeTrainer, Gangster mod and slow motion mod along with pedestrian riot which all work fine, but this mod seems to crash my game.
better yet, I don't know how to uninstall the euphoria mod so effectively i can't play gta 5 anymore..
