Sorcery Transformation Glitch

Device info: iPhone/iOS 12.1.4
Game info: Siralim 3, v. 1.3.17

So, either I’m missing something, or there’s a glitch with Sorcery Transformation on the Sorcery Shapeshifter. It’s supposed to make enemies lose mana when they gain any, and make my guys gain mana whenever they lose it (drained or some such, not spent). Instead, when I use Drain Mana, while it does drain the enemy targets mana, my creatures lose 15 mana instead of gain it…

Thanks, this will be fixed for the next patch!
