A/B test glitch just cost us 1,200 leads and taught me a lesson

Last Tuesday I ran an AI-driven A/B test on our landing page headlines in Columbus, and the tool silently swapped the tracking code mid-run. It didn't throw any error, just kept serving variants for 48 hours with zero attribution data. I only noticed when our dashboard showed a suspicious 1,200 lead drop. Has anyone else had an AI marketing tool fail silently like that, and do you double-check your pixel snippets before every campaign?

Ugh that silent tracking code swap is brutal, I've had similar stuff happen with automation and it's always the quiet failures that sting the most. 1,200 leads gone with zero warning is a gut punch, hope you can recover some of that data from server logs or something.
