v0.11.2 works!

That's because WhistleStopFactories adds recipes before it creates the subgroups for them, which breaks the new recipe generation, because I didn't expect anyone would do this. It sounds like a fixable issue tho, even if it's probably gonna make the code a bit messy.

Should be fixed in 0.12.2.

Still getting the error in 0.12.2
Game with Bobs, no Angle

Confirmed, but the error message differs:

This is actually a different issue I caused while fixing the original... Anyway, this is trivial to fix, so I'll make a release in a few minutes.

There, should actually be working in 0.13.0.

It works, at least before the current update of WhistleStopFactories :-)))
Thanks!
