Ok, so the current brick saving system is really lacking. It saves bricks, events, colors etc just fine. But I've had quite a few issues with ownership. From my understanding it saves the ownership on every brick that is not supported by another brick. This would be fine, if people couldn't build on each other's bricks. But you can, so, the system needs to be changed. Hence, my suggestion.
A separate brick saver that saves the ownership on all bricks.
While I realize the default brick saver works the way it does to save space, It does not work well for long, drawn out community builds. Ownership gets screwed up, and you have to resort to add-ons like the duplicator, or setBrickOwnership to fix it.
Anyhow the end result should look something like this:

Except it would look like that throughout the whole save.
I hope someone can make this. And good luck to those who try.
