I've tried to install the aur package, but for some reason I don't understand,
this fails. 

==> Compiling done.

xz: (stdout): Write error: No space left on device
bsdtar: Write error
==> ERROR: Failed to create package file.

I'm not sure what device that would be, since there are 20 gig left on my hdd.
But anyways, since you reproduced the bug already, it doesn't matter.

If you could fix the save game, that would be great! I realy enjoy playing :)
Maybe you could write up some short howto so I can fix it myself if this happens
again.

Thank you and all involved so very much for this great game and the great support!
