A module Identity does not exist for this module

See original GitHub issue

A working module deployed and configured gets removed its identity as a separate module. This affects the behavior of the solution as it expects data in the twin to properly work. Modules are named as NamedModule (Uppercase first letter) and after the unexpected change, a new namedModule module identity is created. A workaround to recover the module is to create a new identity module manually with NamedModule name, although twin properties are removed and it impacts any dependant state. This workaround is not acceptable in a production environment.

Expected Behavior

a functional module should not be changed, and module identity should remain as initially created.

Current Behavior

A module lost while connected to IoTHub its identity and it is created as a separate module

Steps to Reproduce

No specific steps defined this state. A working module moves into this behavior after some time. It may happen when new modules are deployed. We have experienced this behavior many times, before and after GA.
