Physics simulation won't run until the last frame of the timeline I am making a rigid body physics simulation. It started out ending at 250 frames, but I later changed it to 400 frames. 

The problem occurs when the whole animation stops at the 251st frame. Is there a certain setting for this or do I have to restart all over again?
The rigid body simulation does have it's own start and end.



In the 'Rigid Body World' settings you can change the simulation start and end.
