I did restart the sim an hour before the party started but when I arrived we had a lot of lag.
I did check the visitor's scripts and the scripts on the sim but that gave not a clue why we had so much lag. Suddenly it was over and every body could move again and the chat lag was over to.
DJ Infa had made a great set of music and Tim took over for the after party. We had a great party and wonderful guests, dressed in theme.
Here are the pictures I made.
