Thanks for the response
Most of the buildings reset. Normally I do log off and restart the server between visits, but I THINK it even reset after leaving and returning later.
When I say reset, I mean oddly SOME of the fields and buildings stay (only about 3), while the rest and upgrades disappear, and I have to build them again.
Also, no matter how much I build things, my population never seems to go up.
I've never done castles before, so don't know if I'm supposed to do anything OTHER than build for that, but it didn't go up. I even built stuff, and came back hours later, no population still.
