About
I was running low on ideas and ran into this post on r/minecraftsuggestions which gave me something simple to add to Minecraft.
The mod is a multiplatform mod whichh uses a single mixin that modifies the SpreadingSnowyDirtBlock.class's canPropagate() function adding an additional check for Coarse Dirt after its normal checks.
