Some frequently asked questions.
I left the game for a bit and when I came back I was in a different place! When you die, you respawn by default at Vieda Port. You can change this option in the options tab.
But I was in a town!
Not all towns are completely safe :)
I found a key item, but the Crystal Sphere icon hasn't changed.
Some areas have more than one key item. Also, you may not have the required skill levels to get that item so don't worry if you left the game on overnight and the icon is still there.
