Hey -
I tried testing this by calling function on LMB click. With 4 players I only saw PlayerState as NULL once however Controller->PlayerState was NULL as well. After next frame when I clicked again they were both “ok”. This only occurred once out of about 15 tried with four players each time. all other attempts showed all players as ok when I clicked. How often are you seeing PlayerState as NULL with Controller->PlayerState being ok and is there anything else that might increase odds of this occurring?
