If you choose 2 great maws.
And use the spell on 1 great maw, it takes away your spell from the other great maw. Without using your 2nd Great Maw
It’s obviously cast once, but this is obviously per troop, and not accumulation of 1 cast ends all troops .
Been a bug for years, thought I might mention it, as you guys just messed with the valraven. Bug not bug.
So maybe your just, 5 years behind.
