So, in the September Event news post, Xylax mentions this:
"-Cotton Root Bark will override any fertility boost/debuff
- GMO cow WILL override CRB's effect BUT it most likely WILL make GMO's mutation rarer if CRB's % triggers. So they benefit each other you could say, IF they both work at the same time. Each item has its own % chance to actually trigger, they may fail however.
- GMO Cow will override Bark's % and use cow's % mutation chance BUT the bark might make the mutation super rare."

I have a CRB, and planning to use it with a GMO Cow, but there's a problem. I don't know how to stack them together!
I'm nervous to use CRB since it's my first time using it, but I'm not using it until I get another GMO Cow.
I'm wondering, are these the steps of using the CRB/GMO Cow stack? (Please correct if I'm wrong c:)

1) Let your chosen lioness become pregnant.
2) Use the CRB on your lioness for a miscarriage.
3) Once miscarriage happens, wait until she can be breedable again.
4) Use GMO Cow on her before you breed.
5) Breed her until successful.
6) Ta-da?

I would like to know, as I don't want to waste my CRB or waste my GMO cow if I done a step wrong. Thank you~ <3
