After following that link to another, I realized I should try to find any mailboxes through Clean Installer...not my downloads folder which was nearly impossible. I deleted all three custom ones just named "MailBox" and so far I have no pink mailboxes and I am able to re-zone the lots again. Thanks for your help Naria! 

I haven't downloaded a hack in awhile, but I do download custom lots. About a month ago, a pink mailbox has popped up in my game, especially on my apartment lots and now my tenants no longer pay rent! I think it came with a lot, but how would I find out which one? I really want my sims to pay rent...that's why I bought Apartment life!

Any suggestions or solutions would be greatly appreciated! I checked to make sure there wasn't already a topic on this, but I didn't find anything specifically. Sorry if this is a repeat!

Thanks!

I want it, but i'm scared I will play it more than actually attend class.  I already struggle with balancing TS2 and homework!
