afitts:

There is a difference in what the total_mass() reports when using a snapshot from a single file and a snapshot from multiple files.  What's even stranger is that if you query total_quantity("PartType*_mass") both the single and multiple file snapshots match up. The corresponding snapshots and script can be found here: https://www.dropbox.com/s/2t5pzgwgc7fug9n/massbug.tar.gz?dl=0
