In Agios Cephas, somewhere between the bigger and the smaller trigger circles, there is an invisible object that has an Opfor allegiance.
In the picture attached the outer trigger has an alarm buzzing when Opfor is present. In inner smaller trigger, which is also activated by Opfor with a different sound, indicates that no object exists in its section.

I am wondering if any of the shacks have an faction affiliation by accident or an object is embedded in the map somewhere along its height? {F18415}
