I hope i can explain it well enough.
Add a variant with a comment = 1 order row
Add same variant with same comment = 1 order row
Add same variant with different comment = 2 order row
Remove 1 of the order rows.
This will create a 3 order row, with quantity -1 and minus price
Litium allows adding order rows of same variant with different comments, but not remove if it’s 2 variants with same id, but different comment.
Or am i missing something in the removal part?
