No, the AI objects aren't disabled. They have the incorrect skin settings applied, I think based off team and if they are spawned from the master or remote client. The transforms are fine and within the boundaries of the NavMesh.If there are hierarchy AI objects that are either disabled or enabled from the other Game but can't be seen, then you need to figure out why they are not visible.
Are they disabled? Have incorrect skin settings? InvisibleShadowCaster/PerspectiveMonitor settings making the skin invisible? Are they at some far away transform?
What is your scene set up? Are you using one of the Demo scenes to create this? I would advise against this because particularly with Deathmatch AI kit there are other things which may affect spawning and such.
My scene is a pretty simple setup that I have run through the Opsive tools for setting the layers, managers, camera and everything else. I have also run the scene through the Pun Addon scene setup tool.
I do have my own launcher and room creation scene as well where the players (up to 4) join a room and start a game. Right now, the AI is spawned for each player, not just the master which I think is part of the problem. I have run my character prefabs through the character and the pun Addon also so they are set up correctly now as well. After I added the transform monitor component, I added the others so the Addon didn't really do anything else I don't think besides set the layers up, I'm probably really wrong about that though.I would advise creating your own Launcher and Room creation script leading in to a simple scene that only has the basics - PunGame and what ever other components handle the Pun Spawning.
