Hello!
I added to my pack a multiservice NPC:

 

It allows to player to change his baseclass w.o cheking if he already have that class as a subclass, so this happens:

I tried something like this:
 

			else if (newClass.equals(player.getBaseClass()))
		{
			player.sendMessage("You already have that Baseclass! Choose a new one.");
			return false;
			
		}	
			else if (newClass.equals(player.getSubClasses().values()))
		{
			player.sendMessage("Delete your Subclass first!");
			return false;

 

 

But this is not working. Any help?
