On the second mission of the 4 horsemen campaign while flying on the optional portion of the mission of providing overwatch for the broken down vehicles I encountered two bugs. The first bug was on the first playthrough after I took the enemy out and my character never called the HLZ clear, the helo still came, landed the troops were still on the ground, and nothing happened further. The second time I took the enemies out, my character called the HLZ clear, the helicopter called inbound, the hero came and landed, the troops were never picked up, and nothing happened further.
