What you were expecting to happen, and what actually happened:
When a troop is full of mana the board-facing side pulsates with an arrow, indicating the troop is ready to cast. I’d expect that to be OFF (given it’s so predominant) or have no animation if the troop is silenced (unable to cast).
How often does this happen? When did it begin happening?
Every time.
Steps to make it happen again
Tricky, but you need to play a team with silence ability. If a mana-full troop (ready to cast) gets silenced, the pulsating bar is still illuminated. This is confusing.
