Renamed the default routing parameter "event" to "rng_event"type" to prevent possible clashes with custom entity routes which use "event" as a routing parameter.
This seems related to #175 and #176 ... not yet merged, but will check deeper... I have merged those PRs, and am trying to work out some entity updates, and bring all this back to Drupal.org.
References #168
