In my code, I am writing this : GlowAPI.setGlowing(player,GlowAPI.Color.AQUA,players);
So for every players in my team, they see the others in the team in aqua. But for some reason, they seem to be seeing the other team in white when they crouch / after they crouch for some time
I mean, this is actually the only part I am using of your code... I have no listeners on Sneaking
The players should only see in Aqua the other players of their team.
