Printing Error in Player Core for the Inventor Feat and Machine Magic Feat from the Playtest

[ScubaSteven]

In the playtest, we had a level 2 feat called "Machine Magic" which is not present in the Player Core Book, PDF, Nethys, or Demiplane for the official release.

You can craft hybrid items. When you select this feat, you gain
formulas for four common hybrid items of 2nd level or lower.
You must have the Inventor feat to craft hybrid formulas.

Then, in the Inventor Feat from both Playtest and the published Core, it says:

INVENTOR FEAT 2
DOWNTIME GENERAL SKILL
Prerequisites expert in Crafting
You are a genius at Crafting, easily able to determine how things are made and create new inventions. You can spend downtime to invent a common formula that you don't know. This works just like the Craft activity: you spend half the Price of the formula up front, attempt a Crafting check, and on a success either finish the formula by paying the difference or work for longer to decrease the Price. The difference is that you spend the additional time in research, design, and development, rather than in creating an item. Once it's complete, you add the new formula you invented to your formula book.

The GM might allow you to invent uncommon or rare formulas, typically with an increased DC. You need the Machine Magic feat to invent hybrid items and the Magical Crafting feat to invent magical formulas.
Source Player Core pg. 222

So, my question is. Was Machine Magic forgotten in the Core release, or was it removed, but Inventor should have had this reference replaced with something else?

If I was to hazard a guess, they might be moving it to the tech core?
