Hey guys,
I'm making a map like beacon defense, where you place your flag beacons to get your units, but after 2 minutes or so,
a flag appears on every flag beacons i create and it's impossible to place any other flag beacons.
So, what's up with it?

That's just how flag beacons work. I dunno if there is any way around it.

As Norm said that's how they work. And there's no way around it. Would be used a lot if it was possible.
