Crashing + lagging = Me angry.

Yeah I had a major problem because of this.... before i redecorated i was crashing alot, and stupid me went and bought nearly 100+ fences and trees yesterday too make it worse, I had to remove most of my tree's and fences like over 400 items even more then i bought to make the game stable again, It seemed fine when i tried the freind bonus after removing the items but i think it was just luck that made it work i tried countless times before and every time landed a crash within about 10 mins of entering and existing a town
