Saved reports lose all their formatting on the production deployment when saved as HTML.
This is true when accessed via COGNOS connection, in a portlet or going to the list of saved report versions.
If I render the saved report in a Workspace then it appears properly.
For example a report containing a simple list object with standard formatting correctly applies the css file to the html when run from scratch or when rendering the saved version in a workspace.
When the same saved report is viewed in a portal or from COGNOS connection it only shows the text of the report with no formatting at all.
Is seems that it is not applying the appropriate style sheet.
In our dev environment it works fine.
This is in COGNOS 10.2.2 on windows server 2012
