Okay so in The Sims 3 I killed one NPC by walling him up in my house.

Now I wanted to see what would happen if I did it to two or more Sims, you know putting them in the same room with only one chair and one bed and seeing what they would do when I locked them in there. To my frustration for some reason now every time I wall up a sim they are just able to walk right through the walls and leave the house! Where is the fun in that?!

I don't know if it is because I installed the generation expansion pack or what. That doesn't make a whole lot of sense since when I killed that one Sim I had the Supernatural Expansion pack that came out later and all of the latest patches installed.

I really want to see what happens when you lock three sims that you don't control in a room together but for some reason I can't.

I know this is a minor problem but I really hate it when a game that otherwise gives you the freedom to play the way you want takes that freedom away and "cheats" to keep you from playing a way the makers don't want you to.

That is what I call frustrating.

That's what I did before but now the game is just letting the NPCs walk right through the walls and out of my house and I have no idea why.

I hate it when games change the rules when I am in the middle of playing.

I am trying to have an evil Sim here and the game will not let me!
