Yeah, sorry I didn't realize it when making the video! I swear to god I remember it always spawning in the same area... Thank you for pointing this out! But if you're having trouble finding it, if you noclip under the map, you'll see a green box, and right above it is the backpack!

@Headshot-pc7mz I missed it the first time playing that quest, but I found it the second time because it spawned in a visible location.

@Headshot-pc7mz you are helping us players a great deal man, the only walkthrough that I found for this mod is Wavey's gaming adventures, and you can tell that he missed a lot of quests, while you covered all the angels of each quest, any one who watches your guide should be thankful for that.
