New favorite datasheet...

I noticed my NGS->GPX program was crashing when I was reading a file. Couldn't figure out why, and after some trial and error, was able to find the datasheet that was causing it:

The 'Current Survey Control' is... well, completely blank. I love it.

It does make me wonder though, why have an entry in the database when there's absolutely no location information? Not even scaled?
