I have something strange and cant figure it out by myself. I have 2 maps in my saves that I can't open. I have played on them, but one time they where gone so I searched for them in the Minecraft folder, and found them. There was nothing strange with them, so I don't really get it. Does anybody have an idea about what's wrong?
And sorry for my bad English it isn't my first language :)
edit-- Mrlemon is right, i found them in the map but cant open them in minecraft itself. i compare the 2 maps with one that i can open in minecraft (and see) but dont see a diffrents in between those ill show u guys some screen shots of it.
