"...but I managed to throw your mail in somehow."
My current Sim is residing in the Culpepper apartments. As soon as I got the notification from the mailsim, I went to the apartment atrium/common space where the mailboxes are each in a row on a wall for each apartment, and when I hovered my mouse over my Sim's mailbox, the "Pay bills" and "Get mail" options where grey and I couldn't select anything.
Where is the mailsim "throwing" my mail? Where can I find it, if not in my mailbox? Is this exclusive to the City Living expansion / Update? There is no option to "Pay bills" when selecting my Sim's computer.
