Yeap sometimes happen to me...

Back at university, when I was learning to code, this used to happen to me so fucking often, that now, if some new code is not working right, the first thing I do is always double checking if I'm even calling it. It became like a habbit

Only the best compilers for the most staticly typed languages tell you whether you got orphaned code...

Happens to me a lot. Was pissed at my react.js code not doing anything today until I realized I had a missing / in one of the import file paths

similar thing happens to me with unity. I write a whole script and then forget to add it to the gameobject
