twice now, we've had the boss for this guy spawn in a co-op game (once on rainstorm, once on drizzle). Both times, only the server (me) could see him and be hurt by him. The other players could hurt him if I told them where to shoot, but the boss couldn't hurt them no matter how hard he tried. After he was killed only the server unlocked the miner, my two co-op partners didn't get the credit.

So, I guess, be aware that the unlock may not work for you if you are in a co-op game.
