This is by design. Naninovel is not aware that you're using the texture assigned as background in a UI and unloads it to prevent memory leaks. It's generally unusual to share textures between backgound actors and UIs; even if the texture has similar content, you'll usually want to resize/edit it a bit. If you still want to use the same texture, check the guide on how to notify Naninovel, so it won't unload the asset: https://naninovel.com/guide/resource-pr ... -resources
