TB UNLRA HQ - AI below the map

Didn't happen to catch a screen cap of it last time but the last 2 or 3 times I've visited the TB UNLRA HQ there has been an AI below the map in front of the front door. I know this because the runs were at night and i could see the AI flashlight in the ground. I was able to kill it each time with a grenade. Noticing AI behind on the back deck area too shooting at me but i wasn't able to find them. Maybe they were off the dock in the water?

Anyone else happen to see this?
