What you were expecting to happen, and what actually happened?
I expected to receive 50 extra gold income on ascending a kingdom to four stars. It doesn’t work, for any of my kingdoms. I’ve paid a bit more attention now with Khetar, the four star bonus only activates once a kingdom is ascended to five stars.
What are the steps to make it happen again?
Ascend any kingdom to three stars. Keep note of the income, both for that kingdom and in total. Ascend that kingdom to four stars. Note that the income doesn’t change. Ascend that kingdom to five stars, rejoice in 50 extra gold.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
