What you were expecting to happen, and what actually happened
I used Glory to buy the Frost Archer in the shop several times Monday. I got 2 x 0 reward (see screenshot) and 1 time it said I I even got Freya but I only have 1 Freya so I don’t know what to trust.
How often does this happen? When did it begin happening?
It only happened Monday at a time when the servers seemed laggy.
Steps to make it happen again
I had the three weird experiences Monday but haven’t seen it since.
I’ve had this happen several times also. On xb1. Luckily it’s only a visual bug because whenever it happens I check how many of the troops (in this case Frost Archer) I have and it’s always the correct amount.
