So I'm wrapping up for the day and right before I leave a coworker comes up to me with a problem. Our company uses barcodes to track some of our products through their development and we recently switched over to a new system for producing them. The barcodes for this particular product are supposed to have 8 digits, but the last 200 we printed have 9.

I immediately panic because I wrote the script that generates the bar codes and there had been a bug in the past where the script would add extra leading zeroes that weren't supposed to be there. I scramble and check the database, it would be a huge headache if our production database had been compromised with junk barcodes. Nope, all the new barcodes there have the right number of digits.

Next place to check is in the code that writes the barcodes to a text file for staff to print the physical labels from. Nope that's all fine too.

I ask the person who printed out the recent batch of labels to show me how the printing software reads from the text file. She seems confused by my question and shows me how she manually enters in the barcode range to the software. As she does this I watch her add an extra zero to the numbers. 🙃

Even worse there was an option to import all the codes from a text file literally RIGHT BELOW the manual option.

TLDR; Thought my script had screwed up our database, ended up being the fault of a coworker who didn't know how to import text files.
