Error while running scripts/recon.py

I tried to run the script on different systems, but I always encounter the same issue.

One CPU is a special case that is not handled properly by the script at the moment. For a quick fix, try a droplet with more than one CPU. I will push a proper fix this afternoon.

658695073007886ca68728c055e49e3f6810f0e1 should fix this.

Yup, it works on a higher-spec machine. Thanks!
