Two brainfarts that resulted in... a lot of pain

I had been coding all day, ~6hrs. I was in the zone, so I hadn't saved to git. It was all uncommitted changes (you see where this is going...)

Brainfart#1: The code used the "Contact" class, but for some reason my hands typed "Product" in this ONE line.

Brainfart#2: I became aware of Brainfart#1, so I changed the variable from "Product" to "Contact". However, I instinctively pressed F2, "Rename Symbol", instead of just changing the variable I was using. Now ALL of the references to "Product" were to the "Contact" class instead, across all of our code.

I finished coding. I committed and pushed the changes, closed the IDE, and left the desk for a snack. When I came back, the automated tests were failing due to an import error. That's when I noticed my mistake. I couldn't do Ctrl+Z because I had closed the editor. I had to change the names one by one across all of our code. "Contact" and "Product" are probably our two most used classes 😭
