3-segment wallpapers doesn't seem to work

[ilverogattuso]

I am quite fond of this app, which is why I decided to give it a try and make my own custom themes, that's when I spotted what I think is an error, which is triggered when in the .json you only include 3 out of the 4 Image Lists (in my case I included all and omitted sunrise), afterwards, when selecting the theme from the app, an error will pop-up, so when checking the log it mostly says:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

The current workaround is to include all 4 phases and repeat one image number in the .json, I tried this with sunset and sunrise as well as sunrise and day, and that way it works just fine!
Just wanted to know if this happens to anyone else.
Anyways love your work sir and thanks in advance!
