I am pretty sure while signing up for the beta I read the game would be wiped after our playtime, which is normal for beta testing as we may run into bad bugs (in theory, so far its been playing great!). Now I read in the chat there is no wipe, random people in the chat room is not a good source of information for this =/ could it be an announcement?
I did not really bother placing buildings on the right/best spot since it was only a beta, is there some way to move buildings after having placed them?
