Slabs Recipes not WORKING in v1.12 or v1.14
If you require a copy of my files I can provide it to you, just let me know how!
If I am not mistake when I made the move to 2020.2 I tested the slabs and recipes and I believe they worked!
I also tested my 1.12 version in 1.14 but converting it and the problem still occurred
In the 1.14 version I created a new slab and recipe and they seemed to work but none of the previous ones did!
I replied in an older issue about this same problem, however decided to re-post as the other issue stated you could not recreate the issue again.
Sorry, I know you are busy!
