# Troubleshooting

### Multi-scene setup

* When networked entities are added by loading a scene additively, mind that the `CoherenceMonoBridge` must be set to a *singleton mode*. In case of a non-singleton *monobridge* the Entity will search for a *monobridge* instance within its scene, and if none is found it will be created in that scene. This applies to both `CoherenceSync` and `LiveQuery` objects.

  For a complete control over `CoherenceMonoBridge` resolving you can use either `CoherenceSync.MonoBridgeResolve` instance event or `MonoBridgeStore.MonoBridgeResolve` global event. A `CoherenceMonoBridge` instance provided by the `MonoBridgeResolve` event takes precedence over the scene and singleton ones.

### Baking

* Sometimes packages cache gets staled and after updating coherence package you might face Unity still uses the old package version. Try to `Reimport all` or closing the project, deleting `Library` folder, and reopening the project again. It will clean and update packages cache, and use the version of coherence stated in `manifest.json`.
