Description

Greetings.

I have come across a peculiar bug which always happens when I execute commands following the order specified in the attached file bug.txt

Basically, it ends up not only creating lots of files in order to store just one entry, but also gives erroneous output to certain queries.

I think it is related to the "compute stats" command.

Hope this helps
