It’s not a massive issue if you know the source of the problem, but if you rename a map in the content browser and it’s one of the default maps in the maps and modes section in the project settings, whenever you launch the game, it crashes the game and then the editor, losing anything unsaved. The feedback does say it can’t find the map name, but first thing people generally do in this case is search all their code for references to the old name. Would be nice if it just updated the default maps portion on its own since it’s directly linking to that map anyway. Otherwise a notice in the log that says “perhaps its a default map that needs updating?” would be nice.
