There is an abandoned safe mission that keeps popping up, sometimes multiple times a restart. It is always in the same place but when we go there we cant find a safe anywhere.
We think the safe may be underground which is why we cant find it. I have no idea who's base it is or was.
It's just above the West trader, I haven't had a coffee yet so cant work out why I cant post a screen shot, I'll try again tonight.
