I tried to replicate this issue today, but did not succeed - although I may have found a different bug. I had managed to complete the fleet defense operation and Dust Lance and had moved on to the counterattack phase. I then crashed my plane and retried from a checkpoint. In this, I still had the Allied Support Select option. I pressed down on the D-Pad, but nothing happened. The visual bug from before did not happen, but I also did not notice any allied support occurring.
