I just did Crota last and get the last necessary energy to fully upgrade my black hammer, when I did it, I noticed that the yellow border that shows that your weapon is fully upgraded wasn't showing, also I noticed that I had the option (Y) to upgrade my weapon despite the fact that it;s fully upgraded.
I put the sniper in the vault and pick it up again but the problem is still there.
Any help?
Thanks

This is normal. The Hive Disruptor upgrade was removed due to interference with White Nail, and now the weapon cannot have the gold border.
