### Sonity GUID

Sonity uses cached GUIDs for object comparison.\
This solves problems where object equality isn't always the same when using e.g. addressables.\
The Sonity AssetPostprocessor automatically saves the GUIDs for objects.\
If you have any missing GUIDs (when upgrading) you can run:\
"Tools/Sonity 🔊/Tools/Reserialize - All Sonity Assets".\
