The Sims Help!

Hi Simmers!  I am just going to post issues I have been having in The Sims 3. If you know how to fix these problems, please let me know! Also, wanna talk about some things I dislike about the game. 

1. In Generations, if my children get grounded, it sometimes says they can't leave the house. That means, I can't make them go to school. But if they don't go to school, they will STILL be in trouble for not going to school. I think that is stupid. I make them go anyway if I can sneak out. But it's a bit difficult to do. 

2. When my parent sims go away on a free vacation, I thought it would be cool to for my kids to skip school while they are away. But when they come back, they know about it and my kids still get grounded! That's lame! Not to mention the teens always get caught past curfew and doing pranks. Can't the teens get away with anything? I don't even bother doing the pranks because it will just ruin the relationships. Wish the teens could get away with it at least some of the time. 

Also, when the parents come home from vacation, they expect the house to be clean. But if the house was messy when they left and they return to the same mess, they still ground my teen! And sometimes I lose the parent(s) and they never return back home! I had to restart my game because the mom never came back. It kept happening and I had to start all over again from scratch. 

3. I've been trying to create a dorm for a couple days now, and it won't let me save in the University town. I have to go back to my Home and save there. But when click to go back home, it loads forever and then my laptop shuts off. It happened 3 times. I just want to save whatever I'm doing in the town that I am in. I really liked how it was turning out but now I have to redo it all over again. Ughh!
