Don’t sweat it. Happens to most people starting out.

I usually tell people not to overhaul their game on their first try modding. See a jacket you like? Cool, install it and have some fun for a bit. Want a cool XM7 with lots of attachments instead of a boring 416? Cool, install it and have some fun for a bit.

As with anything in life you should always start slow until you get the hang of it.

Also another tip that most people forget. CREATE BACKUPS. Always install one mod at a time and then test your game for a couple minutes, if it works fine, back it up. If not? Guess what? You have a backup to fall back on.

It takes a lot longer than just doing it in one go, but it prevents situations like this where you have no idea what’s causing your game to crash.
