In my last match (Europe, around 23:00 CET, on Xbox One) I was trying to land a key ghost in the machine. When I hit A it might have been that I just had lost line of sight. The issue is that after that I couldn’t summon anything any more. Pressing x, b or A while holding LT was doing nothing. Needless to say, with me not being able to summon anything, we lost.
I was using the elite controller, hair trigger (but this hasn’t caused any issues with halo wars 2. It had in some other games)
