Gunrunning Bunker Raid

I don't know if this has happened to anyone else...

But I was running supplies alone, and the stock was going to be full within the hour.

I got the notice to go recover my weapons and instantly went to the location to recover the supplies. I did so in record time and brought back the supplies... and yet I fucking lost half my God damn stock? That's a huuuuge fucking piss off man. What the fuck is the point?

Has this shit happened to anyone else? Did I get unlucky? I didn't destroy half my weapons accidentally, I just got a notice that they were suddenly destroyed, which is when I freaked the fuck out and went loud. And I didn't take too long, from the time I got the mission start to when the weapons were destroyed, was maybe, 50 seconds. I was right next to the place I had to be.
