Ancestral Warrior totem is bugged

How to reproduce
- Equip two Ancestral Warrior Totems, each linked to the Sunder skill.
- Assign Weapon Set I to Totem A and Weapon Set II to Totem B. Swap the Sunder gems so that the Totem A now contains the Sunder gem that was originally in Totem B (affinity: Set II) and the Totem B now contains the Sunder gem that was originally in Totem A (affinity: Set I).

The affinity tag stays with the gem and with the totem, so Totem A still tries to use Weapon Set I, but the Sunder gem inside it is tagged for Weapon Set II, so the skill never casts (and vice-versa for Totem B).
