Phew, I have no idea why this isn't working.
Here are my permission files
default.permissions
	
admin.permissions
	
		
		
				chatprefixcolor: 0xFF0000
 nametagprefixcolor: 0xFF0000
 
	 
			Display More
	 
	
I'm an admin on my server, and even if not, the default permissions also have keepinventory set to true. I restarted the server a couple of times now, but in the permissions dialog ingame it's still set to false and I'm loosing my stuff.
Any help is really appreciated. Did I miss something?
