# Description

The `SceneEntityCfg` always return the `joint_ids` and `body_ids` in the
simulation order even if a different order was specified when passing
the names to the `SceneEntityCfg`. This fix changes the behavior, to
always return the ids in the specified order by introducing the flag
`simulation_order` that is true per default for everything within orbit
but false for the `SceneEntityCfg`.

Fixes #461
