Missing Crowns
We are aware of an issue in the most recent update where Crowns are disappearing. The missing Crowns are temporary, as we have records of Crown totals before they disappeared. We're currently working on a solution and will update you as more information becomes available.
You allready have a chat room for 50 allies, just keep them at 50 and randomly add people that join worldwide chat. Will keep the world chat controlled and shouldn't be to hard to implement I would think.
This will also solve the issues with alliances missing the 15/25 wars etc...
It will also help new alliances to be build faster and give them a better chance in succeeding. It's a enormous challenge to build a alliance these days.
