This happened to me 2x in about 3 or 4 hours. I contacted support and they said this was no issue I just didn’t get “tribute” which can happen…
I’ve been playing every day for 8 months and have collected probably over 1,000 tributes easily in that time and I’ve never seen that (or even heard of it) and now it happened 2x in a short period of time?
BTW I have my kingdoms currently as follows. Star levels 1 x 9 stars, 11 x 8 stars, 17 x 7 stars and 1 x 5 stars as well as statues around 80 to 100 this just doesn’t seem like it should be possible…
