The reload method didn't made use of 'with_exclusive_scope' when reloading the object. This lead to a RecordNotFound exception, in case the object doesn't met the default_scope condition (anymore) - which is obviously a bug. This quick fix makes use of with_exclusive_scope in the reload method as well. See test for full example.
