What is Happening:
When you transmog set items the specific item of the set will remove that item from the set bonus list making a visual bug that you no longer have the set bonus active.
What Should happen:
The set bonus should be active at all time even if setbonus items gets transmoged.
This is just a visual but no impact on the game, but a few players do get confused.
