Boolean Differences fail

[clicky]

Describe the bug
Boolean Differences do not get sent to the server and other connected clients

To Reproduce

1. Run Crash.Server
2. Open 2 rhino instances side by side
3. Open a shared model in each with different names
4. Create 2 boxes that intersect in one of the instances
5. Use booleanunion
6. Note that the boxes appear in the other window, but not joined

Expected behavior
A boolean union should create a new object and delete the two old objects

Version Info (please complete the following information):

• Rhino Version [7.27.x]
• Crash Version [ 9d99d37 ]

Additional context
Add/Delete events still fire, which makes me wonder if the user dictionary is passed over or new IDs are which confuses crash.
It may be possible
