Error: Island should be awake, after migrating to 0.32

``` rapier2d-0.32.0\src\dynamics\joint\impulse_joint\impulse_joint_set.rs:407:26: Internal error: island should be awake. ``` Not sure what's changed, but my game crashes at this error. All I did during migration, was to change types to use the new glam api. I do actively sleep and unsleep rigid bodies, depending on where they go in the world. I also sleep initial bodies for a set time, to prevent falling through my dynamic terrain. But it all used to work in previous versions. Also seems to hit this assertion error: ``` rapier2d-0.32.0\src\dynamics\island_manager\sleep.rs:124:13: is sleeping: RigidBodyHandle(Index { index: 2, generation: 0 }) note niter: 1, isl size: 2 ```
