HALO 5 ASSAULT 1 BOMB HELP!

Hi. I am very new in the forge of halo 5 and I have some doubts about how to make an asymmetric assault map where the attackers spawn the bomb and the defenders prevent it from activating. My problem is that when the bomb of the blue team spawns the defenders can also take it. In the forge I place the plate that spawns the bomb in the blue attacking team and the receiving plate in the red team. When the game is in the blue plate turns neutral gray and that’s how the red ones think they can pick it up. Could someone help me solve it?

Might have to see it in person to really understand what you’re trying to say, Otherwise I’d advise checking out one of the other forge community websites. FORGEHUB is probably the best one I know.
