Error: Island should be awake, after migrating to 0.32

[hakolao]

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
