Matt,

The sim is a 1024^3 box.  They .yt file is pretty big, as it was created earlier during a halo finding and merger tree building job, but it's only creating 18 projections per dump.  This error came about before even the first projection was created and saved, so there are none in there.

Thanks,
Brian
