I might suggest just removing the kingdom option from the sidebar. Maybe someone else can think of a reasonable way to do that (assuming the data required is even accessible), but I can’t.
Recent changes to the game are severely impacting the approach to collecting. GOWDB was a near-perfect tool for the game as of a couple updates ago, but now people are going to want pages for pets and weapons too. Next update, who knows what else will change that will beg further massive updates to the DB. @Lyya, I love your database and have used it religiously for many months now but, especially since you are not even really playing the game anymore, I think you should feel free to walk away from this at any time. If it is still fun for you, then by all means carry on, but you have done more than enough.
