Conquest Empire State Objective Infinite Contestion

I just played a match of Conquest on Empire State on Point D where somehow the enemy team was being infinitely contested by 1 player that was nowhere to be seen. What I think is going on is someone figured out how to go under the map to contest the point for the whole game. I'm not certain this is the cause but it's what I expect happened. Please look into this as this sort of cheating should not exist. I was playing on base ps5 with crossplay turned off so somehow a playstation player was doing this.
