Ok after bit testing sneaking around enemies I can say that there's a Minor problem on AI behavior. Problem comes when players are hiding again during combat. Current hidden status Works when Enemy is totally unaware of enemy not saying on code because I don't know your codebase. But current Ai can't hide retreating hiding players.
My suggestion is add new behavior for improved Ai.
Routines(uninterupted)
Suspicious(heard something but not aware of threath)
Spot player (trigger disloque \ combat)
Hostile and known, active turma.
Hostile and target Lost but threath known. ( Pursue actively to find threath, but don't engage hostile actions due stealth.)
Target Lost ( resumes patrol routines but remains suspicious)
If someone is unkown threath then it fights only on engagement not taking sneaking its focus. Or search.
*Search for enemies (knows threath in proximinity and search them actively patrolling based on last known location. And aware of threath but does not know player location.
