I don’t know, if anyone has reported this already, but I haven’t found anything. It’s nothing serious, as it doesn’t affect the gameplay.
It seems that the milestones are not shown correctly. I’ve collected more than 50k trophies this week and also got the token for reaching 43k trophies. But the milestone screen shows only about 23k trophies and tells me, that I need another 20k trophies to reach the next milestone (=43k). Same goes for at least some of my faction mates.
