Quotes - Tax field empty - error generating pdf

Well I’m wondering if this is some 8.4.1 → 8.4.2 fix.
The user that also reported the same problem mentioned he’s on v7.X.Y

I am unable to update due to this problem:

After upgrading to 8.4.2 I simply can’t login to SuiteCRM.

So until a confirmation that it has been fixed, can’t test with 8.4.2.
