I think if you are not active for a time your account should not be deleted at once but removed from map and then if you come back you get a new spot with same boosts and provinces as you had. Then rules from deleting an account can be as it is now
It might be an idea to remove the confirm screen for selling. It is annoying if I am going to remove a building to change it with another level of same building. Also it might be better to call it remove rather than sell.
I do hope the save function gets better than what it is now with that really long string. I would guess it has all infor about every building. On forgestats it is a link that is a lot shorter.
Nice I did like forgestats city planner for FoE and was wishing there was something similar for elvenar. So far I have been using excel but that is not the best tool for this
When fighting in tournament it now is harder to see if I have lost troops or not since the bar showing troops survived does not go across when I have not lost any.
There should be a way to see who donated on previous level like you have in FoE for GB there. You should also have a list of AWs that you have donated that are not finished with current level.
