Just wanted to put up an update to let you know the game team is still working on a permanent fix to make original buildings available for returning characters. They are very aware of players being unable to complete Questlines because they are missing buildings required to progress.
I want to thank everyone who replied in my original post tell me the buildings they needed and also thank you for your patience. Your current options are to wait fir the fix, which I advise, or to open a ticket with support requesting the buildings you need. But please try to only do this if you have an excess of Questlines building up, otherwise support will be flooded with these kind of tickets. This sometimes means issues where players need urgent help get lost in this influx of non urgent tickets.
Thanks in advance.

Yes it’s time for us to gather round and take a look at all you will encounter in the Main Questline.
