I was expecting some sort of “Ai discovers new bug in 30 year old software”… cool I’m excited.

Then they were talking about how the bug was persistent, and I’m more intrigued “is the bug some weird emergent behaviour corrupting state somewhere?”

Nope, just another example of a shit in shit out data model.
