Minion/Monstrology Bug
I've come across a serious glitch when using Minions and Monstrology cards during combat. (Note: This is not related to Myth school being allowed multiples and other schools are not).
If you cast a Minion spell first, then use a Monstrology card, there's no problem you will have both creatures assist you no matter which school you're playing.
BUT If you use a Monstrology card first, then cast a Minion spell, your Monstrology monster disappears. If you use another Monstrology card, you can replace it but of course you've just wasted your first card.
