"No reader function for tag object"

[ulyssesdotcodes]

Repro:

1. Create a prefab out of something with ArcadiaState during Play
2. Restart the play and reconnect nrepl

Expected:
3. No errors, prefab is instantiated like normal
OR
3. Error that explains there is stale ArcadiaState.

Actual:
3. "No reader function for tag object" error

If ArcadiaState could be automatically stripped when creating a prefab that would be amazing.
