As a 2 man developer team working on a mono repo with clear and simple architecture, no I have never caused urgent data corruption or seen it happen. That is more something that happens in codebases that are too big and complex to fully grasp. That it has already happened to you in this scenario does not bode well for the future stability of your codebase, in my opinion.

Urgent is an exaggeration I suppose. I have a high standard of customer service so to me it’s urgent, but the data was corrupted for 3 months before anyone noticed so it wasn’t critical.

Ok I guess we just suck, whatever. We and our customers are very happy.
