Getting a crash on singleplayer

[mrspencerrecor]

Hey guys, i keep getting a crash when i try to play my singleplayer world, and I didn't fly or anything, it was just legit survival.

Here is the crash report I keep getting : http://pastebin.com/9iJ8KEcJ

You can try the new version of Java (update 25, you've got 21).

java.lang.RuntimeException: Unknown character ' ' in 'C:/Users/Shelby/AppData/Roaming/.technic/hexxit/saves/New World/mapwriter.cfg:1'

Can you post the content of that file? My guess is it's either a corrupt file (easily fixed) or some weird locale (language) error.

Edit: You could also try to back up your world and delete that file. Someone else posted with that issue last week and didn't post again after I suggested that, so I guess it fixed his issue...? Please post back if it works.
