Sims 2, sims wont go places, says wall or something.?

Okay playing the game fine. Now i told my sims when they get off work go to bed. They wave with a * and foot prints but will enter the house when i say go here. And its will all sims, they leave or go anyplace they wave their hands and saying there is something in the way but there isnt. And its every sim and every room. It was fine a min ago. Is this a glitch? Anyone else have this?
