If this has already been raised, forgive my posting again on the subject...
I may be missing something here, but the only way I can see how much time is left on the premium account is by building something cheap and the timer is then shown in slot 4 of the build queue. This is ok but the bug where the build queue keeps disappearing doesnt help, and we shouldnt really have to build anything to find out how long remains on the premium account.
May I suggest a countdown timer be added to the info under our avatar? Or any better suggestions, perhaps?
