If first craft of that item made is a multicraft it only gets tracked as a basic single craft under "Crafted Items".

Has happened multiple times for me now, 1st craft was a multi x2 but the display showed x1 for that craft then worked as normal from then onward for this one:

Also here you can see my 1st of each type does not match the output I made due to both of them being multicrafts:

Yeah it's an odd one.

hm so only the first craft in a session for a recipe if its multicraft? Otherwise it works? hmm
will take a look
