Was testing separate terminals last night and encountered a funny thing, remember the ‘alternative secure zone’ setup:
In the test yesterday I used them in operation and because there is only one ‘exit’ directly behind the security officer on the medium security stand the PAX cannot enter the secure path towards the plane… The consequence is that PAX leave the secure zone 
and go around the corner again to go through the security station again ending up in an endless loop till the plane leaves 
PAX should not be able to leave the secure zone and go back in again through a security station, so filed a bug (ACEO-6133) for that. Must say that the pathfinding system solves this in a nice way, as the PAX have the urge to go to the plane and go around the corner again and again to make it, kudos!
