Error when saving large slices

When you save a slice, especially a slice with many entities, the process can take long enough that dependent assets see it removed and throw the following error before it is re-saved and accessible to them once more:

[Error] (Editor) - The slice asset ___.slice is deleted from disk, to prevent further data corruption, all of its root level slice instances are detached. Restoring the slice asset on disk will revert the detaching operation.
