Map favorites keep disappearing

I have been playing Kingdom for 4-5 weeks now, and my list of saved favorites on my map has disappeared now four times. I just go into Map one day, and the Favorites list is empty. It has gotten very annoying at this point, because as I explore, I need to save more favorites, so rebuilding the list is no longer trivial.

I use Windows Phone 7.5 and have client v3.07

Is your version of haypi the last one?
Sometimes it happens also to me but all I do is reset the app and it works but I have an iPhone...

This continues to be a problem. I've now lost my favorites list twice in as many days!

AFAIK, I have the latest client - 3.07 for Windows Phone.

I think I will be able to reproduce this. I think the favorites list is tied to the city you are in. If you move to a different city within your kingdom, and then go to the Map and add a new favorite, that's when the list gets deleted. I am going to test this next time my list gets deleted which is happening about every 3-4 days now. I've lost my favorites so many times I've lost track. I think I'm in the 10-12 times range now. I use WP7.5, so I now save my Favorites in a OneNote rather than use Kingdom.
