Getting Gold in Invasion does not guarantee a bag

So we completed a Garrison invasion and achieved gold status (over 1000 points) but we only got a Green and Blue treasure bag. I submitted a ticket thinking that we should have also gotten a purple bag for going Gold. The ticket response was that getting Gold only gives you a chance at a proc for a purple bag, not a guarantee.

So bottom line is that if you get a purple bag, consider yourself lucky!
