Comment 3 for bug 1430945

Can you please attach ~/.config/com.ubuntu.developer.mzanetti.machines-vs-machines/machines-vs-machines.conf

And are you sure this config doesn't still have entries from a earlier beta version that I've sent around before putting it to the store? The first versions I gave you didn't only have 3 stars per level, but > 20. So if the config still holds old values it would try try to search for a 6-star image now.

If you're sure that you wiped this device since then and this config is created by a version that is/has been in the store, then this is a bug in the calculations.
