Woke up this morning any my BP "Simulation" Button is gone! How do I get it back?

Hitting “Alt-S” Makes it LOOK like it’s simulating but I tested an event begin play that destroys one of the child static mesh components, so it’s not actually simulating. Anyone know how to fix this?

Also, is there a way to rotate a physics constraint, as in a wheel for a trailer that has loose spinning wheels but also the wheels twist right and left to go more smoothly into the turn it’s pulled into? Thanks.
