HELP - Map Issues

[Hauken]

Maybe you have some _cache files? check /maps folder.
Also, i think you should try that map with a different name.
And last, you could try exporting its content. You know, to new map.

how do i export the content to a new map?

You select everything you want, then go to File > Export selection
Place the file where you can find it, then go to your other map and select import selection.
