Have you ever felt deeply frustrated after successful assault on enemy faction base because all you've managed to seize in the end were half-empty bottle of vodka and stale bread?
Every trader (except Sidor, Sakharov, Nimble and Hawaiian) has his own warehouse somewhere nearby which can only be accessed after searching trader's dead body.
Do not expect to find exoskeletons or anything of late-game origins in there, only generic trader supplies. Good hunting.
Important! Let trader leave his spot before you go for kill otherwise body might be unreachable in some cases (Zaton Skadovsk, Darkvalley Bandits base, Military Agroprom).
If you are using STCOP 3.4 or/and Inventory Enhance addons - install latest patches before adding this.
1.5r7 crashes sometimes when trader is killed. I have no control of this outside of engine and it has nothing to do with this addon. Only way out is to reload and repeat again.
(Optional) Disable friendly traders invulnerability if loot is more important than reputation.
