Also, the keys & doors update is now live: There are now three different key/door pairs, and keys generated are unique to each city. You can give/trade players keys or have them autospawn. Use them to give only specific people in a city access to a building, or to make dungeons more interesting!
I have added one to the first dungeon, the Law Offices of LOL & LOL.
