animation stops baking at 250 frames

I’ve recently completed a tutorial on animating a flag with wind forces, but when I play or bake the animation, is just stops at 250 frames, no matter how long I set the end point for - I’ve currently got it to end at 500 frames, but the animation just freezes at 250 - it’ll keep playing, but the flag just doesn’t move any more

I really want to make this animation longer, and I can’t figure out how. Help?

Same issue as this for soft body simulation.
