Need help! Stuck at Helicopter-capturing sequence. Bug?

[IceFoxx]

The Mission where you got to the radio-tower and afterwards you fight your way to the helicopter while Lugo gives you backup:

After me and and Adams got into the helicopter, I cover Lugo with the on-board-minigun while he fights his way to us. But at some point, 20-30m infront the chopper, behind a box, he hides there and doesnt move anymore. even when all enemys are down.

what can i do?

[IceFoxx]

okay... uhm... it solved itself.

After some minutes of waiting he finally came out and mission was done... strange

A similar thing happened to me, I just restarted at the last checkpoint

I've played through this game about a dozen times, and this same thing has happened to me probably 3 or 4 times. So yeah... I guess it's somewhat common.
