I doubt that. That one is caused by the model being removed and then re-added. My guess is that somehow the QML side sees all the dives disappearing and then when the first new dives are added after things are loaded it picks one of them as the selected dive - and we load them oldest first.
I have no evidence that this is what's happening, though :-)

One thing we could do when refreshing is remembering the selected dive_id and then selecting that same dive_id again, assuming it still exists. Not something super high on my list of priorities, tbh.
