On Miramar while spectating a duo teammate,I encountered two bugs.
One which happened in the middle east part of the map north of Los Leones displayed the losing "Better Luck Next Time" screen while my teammate was still in game with the screen dimmed with no ability to check the map.
The other bug I ran into was in Los Leones while spectating. From the far west,multi-story building and on,I heard his footsteps as though they were on a metal stairwell the whole time. At first I thought it was another person in his building (because there are a lot of metal stairwells) and after he left said building,it continued till he died.
