title: Dynamics 365 - Plugin - Newly Created Images Are Null when checked in code?
body: <p>I am working on a d365 unified interface sandbox environment on a development project.
  This environment was setup recently as a clone of the production d365 instance.</p>
  <p>Today I have been adding some plugins and finding a strange issue. I can get the plugin code on record create/update firing no problem (I have pre operation create/update and post operation create/update stages defined and the correct code gets hit for each).
  But the C# plugin code does not recognise any of the pre or post images that I have added.
  In code when we check IPluginExecutionContext.PostEntityImages it does not contain anything.</p>
  <p>Any of the pre existing images that were there already when the environment was cloned are firing correctly. We have a process whereby we name all of our pre and post images the exact same for every entity and I know the ones I have created are named exactly as expected.
  In this example I have created a Post Operation stage Update plugin on the OOB opportunity entity with a PreImage defined against it but the code just will not recognise it.</p>
  <p>Anyone experienced this before?
  TIA</p>
