It shouldn’t happen before a long time… From @Lyya’s spoiler (until February 1st) none kingdom will have the 9th star…
Because you need 19 troops in a kingdom… and on February 1st, the max will be 17 troops in one kingdom.
I never heard about that. There were a few 18-kingdoms records.
But tribute ratio can be tweaked so who knows what it’s going on now…
