If I click Ember Spray to use it, but then click it again to cancel it without using it, some features of the map become temporarily unusable: line of sight is no longer shown when mousing over characters, and right clicking characters no longer shows details about their attached cards. Normal functionality is restored after playing a card, or by cancelling some other kind of card such as Melt Armor. I've only done very limited testing, but my impression is that the bug is triggered by cancelling 'cone' cards (such as Ember Spray, Magma Spray, Cone Of Cold, etc). The effects of the bug are fixed by either playing a card, or by cancelling any non-cone card.
