I think you saw this yesterday, just documenting until it gets fixed. Log from when tterrag and I were talking about it.

Due to internal changes with Guide-API, any build after 16 will not work completely with BloodMagic. The way PageIRecipe works was changed to be a bit nicer. This, sadly, broke BM's pages as Way was doing it "wrong".

It causes the crash you can see at TeamAmeriFrance/Guide-API#10.

To correct this, PageOrbRecipe needs to implement IRecipeRenderer instead of extending PageIRecipe. You then pass that IRecipeRender to PageIRecipe here.

Fixed in 7d7db0b
