AI confused with multiple AI actors

Just wondering if anybody has come up with this before, if it is a bug or w/e. I have a simplistic working ai behavior tree with 4 states (patrol, guard, investigate, idle) and hearing, damage, seeing senses (AI Perception using ‘On AI Perception Updated’) and a blackboard. All is working fine when a single ai actor is on the level. But when there are multiple ai actors (either of the same or different behavior trees) the ai immediately detects me from the start of the game; event though I’m hidden. Right now what I’m trying to do is push through all the UE4 ai related bugs and peculiarities. Anybody has any ideas with this, because I’m having trouble with figuring out what’s wrong. Thanks.
