Land auction null pointer exception

I was hosting, and someone asked about the land auction, so I decided to go in and show them how it worked. I went into the land office, it told me to mark the plot for sale, so I went out and selected an empty plot and hit space. That's exactly when I got the Null pointer Exception error.  I clicked OK on the message and it blew the entire game out and shut the application down.

You can only mark your own plots For Sale. However, doing so shouldn't crash the game  . When they coded it they probably didn't think about that possibility.
