Specifcally, Druid Mission board, using "Wild Mushroom" item that restores 1 vitality to troops.

1. click the Wild Mushroom in bags
2. click the troop in subsequent pop up.
3. Hear an indicator from teh game, but no change in troop vitality, and Wild Mushroom isn't consumed.

Noted the same behavior when using the Wild Mushroom from the Order Hall Commander sidebar menu.

shoulda done this first. Disabled OrderHallCommander addon and noted problem still exists. Must be another addon.
