"In the Christmas build (v0.0.5), Bara Spheres should not appear in the following battles:
- Against other Bara Chasers
- Against Viadomon (because of the Christmas quest)
- Against Santa Claus
If Bara Spheres are not appearing in any other battle, enter a battle against any Bara Chaser (it can be a rematch), and the bug should correct itself automatically after the battle.
For build 0.07, we're exploring other ways to address the misuse of Bara Spheres."
