Strange BPVLTIME for Ks in data

Running DaVinci!782 (merged) on lhcb-head (Wednesday) and ./run lbexec DaVinciExamples.tupling.option_davinci_tupling_from_data:main DaVinciExamples/example_data/Spruce_Run251342.yaml

I get many nans in BPVLTIME, even when the other variables are fine. So I could actually recompute the lifetime from BPVFD and momentum and not get a nan.

I get

This is BPVLTIME divided by D/(cbetagamma)=D(cp/m). There is a peak at 1, but there are many other events with weird values.
