WMK data extractor not take mbtiles input

Hi Ben,

Thank you for showing me how to extract map properly today.

I tried to extract Illionois map this afternoon. I think something went wrong. After 30 minutes it was still running, the file size grew to more than 1.5 GB. It seems there is an infinite loop somewhere.

Can you please try to see if you can reproduce?

Thanks,

Liang
