My first real user broke the product on day one

A guy logged into Monti on a Mac using Firefox and immediately hit three bugs.

My immediate instinct was to panic, apologize, and start defending the codebase.
I built this entire thing myself, and seeing someone else click around made every shortcut I took feel incredibly exposed.

Instead of hiding, I asked him to keep going and screen-share while it broke.

The bugs were real, bdw. A state-management issue froze the decision input field, and a CSS layout glitch buried the primary action button on smaller screens.
It was embarrassing to watch, for sure.

But as I watched him struggle through it, a weird realization hit me.
He wasn't quitting.
He was actually trying to force the app to work because he wanted to log a decision he had just made before he forgot the context.

Silence from zero users is terrifying.
Bugs from a live user mean someone actually cares enough about the problem to try and navigate your broken software.

Anyway, I fixed the code that night, but the real takeaway wasn't the technical fix. It was realizing that bad code with a real user is infinitely better than clean code that nobody touches.

How did you handle the absolute panic of your first live user bug?
