Missing Maxis lots?

[Ng_pillow 162]

So i actually read wikipedia and it says that cos of some bug, it caused like two-dozen of the largest growable lots of buildings from appearing. So i actually checked lot editor, and i realised i don't find lots containing buildings such as walkup tower, or the primavera. However you still can create your own customised lots with these buildings as the building files for them still can be found in LE. Is there any fix for the missing buildings? Is there a fix suitable for players using steam to play SC4 cos i'm using it?

The two pre-Rush Hour patches each fixed errors in the game code that, while not impeding actual gameplay, were previously preventing nearly a third of the Maxis-designed buildings from ever appearing in the game

What this means is, if you are using Rush Hour or Deluxe, the issue is already fixed. Otherwise, simply install the patches for your game to resolve the problem.
