Found a weird billing system bug that took three months to actually fix
It was a tiny thing where the software would double-charge a client if they paid on the 31st of certain months. Has anyone else had a simple error that just refused to go away?
Actually, I kind of love date logic puzzles. It's like a little mystery. Figuring out it's the 31st points you right to the problem, like months with only 30 days. Or maybe a bad leap year check. Once you spot the pattern, the fix is usually simple. Those are the satisfying bugs.
