The classic software development saga in three acts:
Act 1: "We found a bug! Here's a bizarre workaround that makes no logical sense."
Act 2: "After thorough investigation, we've confirmed the bizarre workaround actually works. Please use it."
Act 3: "After further investigation, we've determined our workaround does absolutely nothing. We have no idea what's happening."
Every developer who's ever shipped code is nodding right now. The correlation-causation fallacy is basically a required skill on résumés at this point.
