CRM 2013: Custom action import failure

Hi,

I have created a Process of type Action and for "None (Global)" so that it can be registered for any entity. On this action I have created a few arguments and set values. This Process is related to nothing, has no dependencies whatsoever. I then created a new solution and added the custom action to the solution and exported it. When I import this solution with just one action, in any other CRM 2013 Org, with or without rollup 1, managed or unmanaged, I get“Workflow With Id ={GUID} Does Not Exist”. This does not make sense to me at all. Are custom actions non-exportable?
