Hi Folks,
same issue here. I can't upgrade prosperity to lvl 3. as all of the doors to the room for upgrade are closed.
Yes I have already completed the 'under siege' mission. Actualy I have all of the missions completed, all requirements for the upgrade to lvl 3 are fine and I have already all of my buddies in prosperity, just the doors are closed...
I know, that the dev. team is already investigating it, but can you please let us know any update? We can't progress the story any further.
many thanks
