What was the worst bug you have ever encountered?

An error with my Python Kivy file. There is literally nothing wrong with it. I even copy and paste the correct version of the code from the tutorial/docs (no difference) and it still didn't work. I still haven't fixed it or found the answer. And it saddens me deeply

the one that still lives on...

Missed some checks so everything had the same id.

Again missed some checks so the "unique" stuff repeated every few weeks.

It wasn't me but a coworker though.

@Bubbles I don't want to sound condescending, but I do this sometimes. Do your python and kivy versions match the tutorial?

@DucksCanCode they do

@Bubbles just checking :D if it's a public repo drop the URL and I'll see if I can figure out what's up if you want

@DucksCanCode I actually had to clarify in the .kv file the version of kivy which is stupid

@Bubbles I've never used kivy but it already sounds like a bag of shit xD.

Not sure if this is a valid answer but humans for me are the worst kind of bugs. Not consistent in the response and almost impossible to debug.
