Thanks for sacrificing your progress to test if reinstalling works. Now I won't be tempted to try it myself...
I've put so many hours into getting all the best gear/weapons, if I lose everything I'm probably not gonna touch this game for a long time.
(This savefile was already the third time I had to start from scratch...)
After the last update(16/11/2015), the app closes after the initial screens, specifically "RakNet™" in lumia 930 with Windows 10 Mobile Build 10581
We need some information from developers. Strange thing that nobody annouced this update. It came in total silence.
