Henri,

Does your consistency issue have anything to do with the earlier 
"Reset" question? I also wanted a quick way to reset the initial 
conditions of a simulation, and I liked your solution of just 
resetting the positions, quaternions, linear and angular velocities. 
So I tried that out over the weekend. I found that after resetting, 
although all the positions and velocities were correct (as i set 
them), the simulation proceeded differently. Is there something else 
that I need to reinitialize?
