SafeKeeper, they always have been able to do that, they will fight any enemy units that are blocking their direct path to safety. Routing units do not think to go arond such enemies.

Ranger, that's normal behavior. Whenever there are tramplers on the field, anything smaller than them, especially commanders, mages and gods should be kept away from their lines of retreat or that's bound to happen.
