What you were expecting to happen, and what actually happened?
I opened a bunch of Event chests (15). I expected to get troops from Leonis Empire only, instead I got only half of them from here (exactly 7/13, 2 chests dropped traitstones).
What are the steps to make it happen again?
Perhaps open some more Event chests?
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
