I had one ally for whom I did not get paid when he was purchased from me. I verified he was purchased but did not get my gold back. Samdubuc is the ally name. It happened at approx 7:55am Pacific time on 3/3 on my Android device.
Did you restart the app? Did you get attacked in the mean time? Also a support ticket would be more your thing if you’re trying to get something looked at and fixed such as this.
