Interesting!
This happened to me coming back from an overnight stay in Luxembourg in early October - I was told I’d overstayed my 90 days, presumably not having been logged as leaving in a previous trip into Europe earlier in the summer. Assumed it was a one-off / just me; they waved it off anyway, and I had no issue going to Copenhagen 10 days later.
Apparently I was not the only one!

@andypiper The whole UK to EU visitor system is a shitshow. And it gets worse. My OH is an EU citizen and the ECtHR ruled that spouses of EU citizens traveling to the EU shouldn't have their joint trips counted towards the 90 days as that would limit EU citizens travel rights. So I can travel anywhere in the EU with them for unlimited time and it not count towards the 90 days, but they don't properly record who I was travelling with so they can't know if I've already used my 90 days or not.
