I'm having a problem with my sims 2 game. i put up a lot of neighborhood decorations (trees) around my lot like this:

but when i play as the lot, this is what it looks like from both sides:


you can't see all of the trees i added to the neighborhood screen. whats going on? I have all the graphic setting put on high, and the lot view distance put on high too. Could someone please help me fix this?
