There appears to be a avatar glitch for master chief collection when using the ODST DLC. When I choose one in the game, a different one is shown here on the waypoint.
When I choose Dare, it shows Buck on waypoint
When I choose Buck, it shows Dutch on waypoint
When I choose Dutch, it shows Dare on waypoint
Hopefully this is a quick fix as it appears to be an association issue with the website and not something with the game. Then again, Master Chief Collection and bugs seem to go hand in hand.
