I'm trying to implement a Parties support to my Fork of UhcCore and to do that, I tried to listen for Parties API's BukkitPartiesPlayerPostJoinEvent, but it doesn't seem to work properly?

This is my simple code I have:

@EventHandler
    public void onPartyJoin(BukkitPartiesPlayerPostJoinEvent event){
        System.out.println("Party joined.");
        playersManager.assignPartyTeam(event.getPartyPlayer().getPlayerUUID(), event.getInviter());
    }

What I'm trying to accomplish is, when a Party connects to the server, using the follow feature, all the players will be assigned to the same team.
However, when I create a new party with my alt account, connect to the UHC Server, my alt "follows" me, but the the error doesn't seem to be fired (No "Party joined." message shows up in the console)

Am I perhaps using the event for not its intended purpose, or am I missing something?
I absolutely love your work on Parties and would really like to be able to use the API in the way I described above.

I am currently working on the new API (Parties 3.0.0), so any fix of 2.X will be deprecated.

I will mark this as working on so I can check if it works once the new API is ready :)
