# Known Issues

### Schema

* Integer values are limited to \[-9999, 22768] due to compression.

### Level of Detail

* LOD levels are not properly updated when queries move or resize.

### CoherenceMonoBridge: ClientCore

* When upgrading older projects to 0.9, you may get the following error after trying to connect to a Room/World: \
  `System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.`\
  \
  If this happens, you should manually select the Prefabs with the `CoherenceSync` component in the Inspector to trigger an update via the GUI (graphical user interface).\
  \
  If you have any problems after trying this, please let us know on our [Discord](https://coherence.io/discord) so we can help you out.
