Could not board chopper at exfil

Two Fireteam boarding the same chopper line at the same time (completion of interaction at the same time on the same line) results in one fireteam member being left behind unable to board remaining lines.

Probably the game thinking the line has already been used and that they should be on the chopper.

I think this a legitimate game feature

Nevermind

One time all the lines were used up but I was still left behind
