The one thing that definitely doesn't get saved is the the difficulty level - ever new game starts on Easy, but that might be by design.
The difficulty level is not a setting at all (and consequently not saved as one) in freeciv < 3.2.
There is something wrong with saving of options in the qt gui. Sometimes they save and sometimes they don't, but it often isn't repeatable and then I'm not sure, etc. The one thing that definitely doesn't get saved is the the difficulty level - ever new game starts on Easy, but that might be by design.
One problem that is reproducible goes as follows:The natural thing the do thereafter is to click Apply, then Save, then Ok. The dialog disappears and the text box (bottom left) displays: "Saved settings to file /home/chippo/.freeciv/freeciv-client-rc-3.0". For the rest of that turn it will not auto center, but after the click Turn Done, Auto-center-on-units is on again. And looking in the options shows it to be on.
(You can work around this by, before clicking Turn Done, going to Game->Options->Save-Options-Now.)
