Changing city schema
Hello. Basic question - when you change the city schema, do you lose the old one?
For example, you have Hecate now. Then later buy another one, maybe higher level or newer. If you change it to something else, do you lose Hecate? same for the original 'free' city design?
Now I also get some mission, 'change city schema for XP', But I dont want to do that if it means I must lose my old schema, have to buy it again.
