Brave warriors,
It has come to our attention that we currently have a live bug affecting the cost of ruby buildings.
The issue will affect all players who have purchased the Single Player Subscription and will cause all ruby buildings to appear cheaper than they actually are. The 10% reduction in building costs is only designed to affect normal buildings but the stat appears to be applying to both.
However! Upon purchasing a ruby building you will find you have been charged the full price.
Sadly this is not something that we can resolve over the weekend, but will look to correct as soon as we can next week.
If you have a Single Player Subscription and purchase a ruby building your account will be charged the full price, please be aware of this matter in order to avoid disappointment!
Best regards,
Your Empire Family
