Thanks, that certainly shows it. Will look at what's up.

I suspect that this kind of merging (that *concatenates* two different
dives into one, rather than merging two different dive computers' same
dive into one dive with two computers) probably never merged events at
all in the first place.

Because it's not just gas changes that are missing, all the other
events are gone too.
