I’m not sure that doesn’t sit well with me.

Rule 1 should be: Reproduce with most minimal setup.

99% you’ll already have found the bug.

1% for me was a font that couldn’t do a combination of letters in a row. life ft, just didn’t work and thats why it made mistakes in the PDF.

No way I could’ve ever known that if I wouldn’t have reproduced it down to the letter.

Just split code in half till you find what’s the exact part that goes wrong.
