[FAQ] Lags & Freezes

Well just spent like 4 days and way too many hours to be healthy on Sims 3 trying to make an amazing hotel (which I was totally doing), but I got so caught up in making it perfect that I didn't save it and then I clicked on a sunflower vase while having the "create a style" tool in my hand it was all like " Can't customize er whatever" and it had some arrow thing pointing @ some kinda * looking thing that was in the corner of that box that pops up in the top left corner of the screen when you click on something to change the color and stuff. I clicked it and nothing happened and so I was all like "wtf is this" and clicked the that check mark thing @ the bottom of that box on the right with all the color options and stuff and the screen made all those boxes go away and I was like " k good thing that **bleep**s over" and then the screen popped up that loading Sims diamond thing and it said "Processing"  and so I was like "%^&*(%!!!!!" and it just kept loading like that 4 like a half hour and nothings happening so like my whole world is like ending right now and I'm calling out to the sim gods er whatever to like help me out like now. PLEASE!!!!!!
