I don't know if this is a Baketorio+ problem or already included in Baketorio, because I only played Baketorio+ so far.

I just tried to make "Peach Cobbler" for my Fruit Baking Science. For "Raw Peach Cobbler" I need "Cobbler Mixture". But I cannot select the recipe for "Cobbler Mixture" in my chemical plants. It looks like learning about peaches does not unlock the recipe for "Cobbler Mixture".

Sorry about that, it has been fixed in last patch

Perfect. Thanks for that.

Btw, in the meantime I managed to modify my local copy and complete my goals. I had a blast.

Oh that's awesome!
I just added a couple other fixes in the previous update, but finished an update now with some... interesting changes XD
