When the underlying dictionary in the network group closure's graph is resized, the master of the entities/groups in the closure is updated without updating the replicables tree.

When persistence/network group closures are split the closure of the split entities and split groups isn't updated, causing future split/merge to be lost server side, causing the replicable tree to be wrong.
When entities undergo group changes the persistence/network group closures can drop unrelated edges, leading to broken closures.
Non top level entities are included when calculating persistence/network group closures. This may not be an issue, but it causes weird replicable tree ordering.
