I'm having a blast with this mod, but I've run into a bit of an issue... should be an easy fix, theoretically, maybe even something that can be handled by tweaking an ini? Anyway, the problem is that Scout Troopers - who drop snake-corpses, ya know - are way, way too rare, and disappear way too quickly. If the game isn't generous with the early-game missions that allow you to recover corpses, you can wind up in the situation I'm in - I literally cannot complete the advanced medikit project. It requires 2 Viper Corpses, I've only got one, and they long-since stopped spawning. I haven't sold or otherwise wasted any, either - only two collectable corpses dropped before they stopped showing up, and one of them was consumed by the autopsy...

I suppose that the root of the issue is that in the base game, Vipers show up in pods. Even though they disappear quickly, just a single mission that both features them and lets you collect corpses is likely to give you everything you need. Scout Snipers, however, always show up alone, supported by a Scout Spotter or Scout Troopers... so they're a LOT harder to come by, but disappear just as quickly.
