I had one dormie who did not come out of his room for a long time, so I used the move_objects and put him outside of his room, then I had this sim girl interact with him and she did not like him so she kept shoving him and poking him and then she kicked his butt, well, then I didn't see him anymore and I looked outside and he was standing at the edge of the lot, not on the side where they exit to go to class but the other side.
Then in a little while I did not see him anymore and their were animations coming from his room, like pictures of the stereo being on, so I went into buy mode so I could see what he was doing and he was not there, just animations. I figured maybe he was hiding behind the door, so I rotated the lot all around and he is not in there, he has disappeared.
maybe he was afraid that girl would kick his butt again.
