Necron repeatedly creates monolith without losing an HQ, thus giving him 3 HQs and monolith HQ. This gives him 4 production buildings that produces more units than normally possible. Secondly, when the monolith dies, the HQ's hit points are unaffected like it normally should.
At around the 19 minute mark necron creates his first monolith glitch, and I think he does this 5 times during the game. Does anyone know how he does this? I've had this bug occur to me once accidentally and I have no idea what caused it, so I don't think it's a hack.
I've tried re-creating this glitch but unable to do so. Can anyone figure this out?
