Ive also heard that sometimes the partial files if they are saved as _01, or _02 it may mess up your map, but if you are having difficulty getting back on back or if your character is just stuck there, click on the "Character Reset" (http://www.feral-heart.com/index.php?option=com_wrapper&view=wrapper&Itemid=55) so that you may get out of your broken or overly packed map.

If you are unable to even get in your front menu page, then I sugest you takeout the last exported map you have put in. Chances are if that's what made your game bug out then you need to take it out to make it function more properly.
Good luck floof
