Invisible force field at the HQ zone line??

I can't say I've noticed this, and I was playing basically all day yesterday. Do you know the CRAM anti-aircraft gun at the HQ automatically shoots down incoming missiles/rockets? That might be what you're seeing, since missiles will explode in mid-air on their way into the HQ, because the CRAM shot them down.

I do agree that there are serious spawn camping and spawn sniping issues due to the small map designs. I doubt they will change the maps, since people complained so loudly about 2042's maps being too big. Maybe an invisible wall is the only solution, but it should definitely work both ways.
