One of the longest awaited updates in the whole history of AAO : characters' mouth now stop when they're not talking !
Everything works automatically, and old trials make use of this functionality too.
When using the editor's default sprites, you have nothing to worry about - it will all be done automatically. When using custom sprites, you can indicate the "still sprites" to use so that this feature works with your custom sprites too !
Big thanks to Kroki for the enormous work he's done, collecting and sorting all AA sprites so that the game can switch between talking and still sprites automatically
