I was just doing a beach invasion with no aegis present and I realized there are still a few permanent flares on the beach; there probably shouldn't be if there are no sec-troopers present. Also, there are a few places in the game where some permanent flares are encountered by the player, like at the entrance to the rathound kings labyrinth, or the spider tunnels under the coretech warehouse; I think these should extinguish once you leave the map and come back.
