Way to disable Black Plague Hearts

First of all thank you for the latest update 37 and the curveball customization and other QOL improvements.

My wish list item would be a toggle switch in the curveball customization screen to disable the black plague hearts, without turning off all the other curveballs.

I know a lot of people like that curveball, but it's a bit over the top to me, and I have not enabled curveballs since it's inclusion, I liked all the other challenges but that one.

The two times I encountered the Black Plague Hearts, the first time it pretty much wiped out my entire community, the second time I actually beat it, but it just wasn't fun to me.

Thank you for all your hard work and continued support of one of my all time favorite games.
