EDIT: nevermind. I forgot to set the player group size :)
I have 4 player combatants. I used the 'Join Active Group' for all 4 combatants in the start up event before spawning the player. Following the HUD tutorial, I created a player HUD. Only 3 of the 4 combatants are showing. The first 3 in the event setup are displaying. Is this a potential bug? Has anyone else experienced this issue before?
