The below image is what I get when starting a new game.
I reported the same bug for version 0.86 https://forums.elementalgame.com/418401
I have tried deleting the files in the C:/Program Data/Stardock/Elemental-FallenEnchantress/Screens folder, forcing an update from the server but although the update worked (and gave me the nice intro screen with people on horses which I was then missing) it did not fix the above problem.
I then tried a fresh install (previously I had the 0.77 updated to 0.85, 0.86, 0.90 then 0.91) but got the same lack of sovereign image when choosing the sovereign, as above.
I realise that not many people have had this problem but I am not the only one.
If I can provide you with any more information to help track the cause of the problem, whether it is with the game or my system I am more than willing.
Fortunately, at least in 0.86, as far as I can tell this problem did not affect the rest of the game in any way. Off to find out if this is so in 0.91...
