What you were expecting to happen, and what actually happened?
I purchased troops using event keys in an attempt to get extra/missing Pan’s Vale Troops. I received Whitehelm and Divinion Fields troops before stopping.
What are the steps to make it happen again?
Open Event Key chest from the Chests UI. In case it’s useful, I’m on iOS 7 using an iphone 5s
Any chance of getting the keys back?
