Oh yes definitely, but in the meantime offering stuff is about the only thing I can do. Any kind of locker system would need to be stored independently of the sanctum because the sanctum is offline, and would also need to detect what is considered “valuable”.
Is it just stuff in storage blocks? Is it also placed coils? Is it literally every block in a build? And then there’s the other aspect of people finding regenerating builds being a part of the game that would be taken away from this.
While I agree a system is needed, the best way to approach it is a difficult task for sure.
