Losing a defend while invading causes stability issues if you check your revenge window prior to the splash screen. Screens shots below. Using iOS
I have a third screen shot of the crafting window with everything off screen to the right. However it is not uploading. Stability degraded as I was capturing what was going on culminating into the above shot. Closed app and restarted with full functionality.
We’re aware of this and have fix for it (currently out on Steam). Unfortunately we didn’t get it through Apple before they closed for the holidays.
At the moment the best why to avoid the issue is to return to the world map BEFORE you go into the revenge menu a second time.
