If no objective is set, the dialog still pops up. Perhaps a default message could be used when none set (e.g. “no objectives set”)
Whoops this is a bug. Actually if you just start a custom game with no objectives the window is not shown. If you add a victory condition and then remove it, then it pops up. Basically I don’t clear the data out properly when you remove the victory condition. My bad.
