Bloodvine (3) tailoring +2% crit does not get properly calculated for classic anniversary

Has anyone noticed that the 2% crit does not get properly added when simulating for best in bags?

I have not noticed this, and I wrote the code!

If you post a snapshot of a case where you think it is not getting activated, we can take a look and see if something is going on. Press the “help” link next to the big Best in Bags section header and copy the generated 32-digit code here.

It looks like you have not set your professions. You can do that by clicking the menu button next to your character name:

The classic addon can’t import your professions, so you need to choose them manually.
