It was only a handful of immediate settings in Aperture Priority I think, mostly I was surprised with focus mode going to servo while I had been using single shot. I'm half-doubting that that actually happened, but almost certain it did. Perhaps I pressed something? It was really hot at the time, and maybe it overheated? I was not able to replicate it and none of the saved settings like Custom functions or customizations were impacted.
Not too bad considering it's a 4k body. But things like this should be covered by warranty, and I guess you've had yours for quite a while? Hopefully no more issues in its lifetime once you get it serviced.
