This would eliminate new bug reports from reloading within the game, and allow you to concentrate on more important bugs and issues.  If you could get FE to quit itself and load up a new version of itself without the previous game's info would be even better.  I now know no longer load or start new games from within a game, and it may be a good idea to enforce this to prevent the memory being used up problem.  Even if you don't re-enable it for release, it may still be good to not support starting new games or loading new games once you've already started a game or a save in the first load of FE.  If you want to tackle the memory issues from having this option later in the beta that would be okay, but I would strongly recommend that you remove this option for the time being to focus your efforts on more important stuff.
