Resolution Note:
The Docs CodeSamples contained a Baker that ran on a Unity internal type (Rigibody). Because of this, when embedded, the component types added to the Entity in the Baker would be added to the EntityScene. But this assembly is stripped on build, so those types are 'missing' when the TypeManager tries to find them. I edited the CodeSamples to fix this.
