Mirage Portal Too Close to Blight Encounters

Every time there's a blight encounter and a mirage portal in my maps, they are always right on top of one another. This is a problem because when I'm running around trying to do the blight encounter (twice, because of the mirage!), the mirage portal is right in my way and I keep accidentally clicking into the portal, and then failing the blight encounter.

Can you please either make it so the mirage portals are further away from the blight encounter, or make the mirage portal not interactable while the blight encounter is in progress?
