Stage View Disappears Completely - missing xml file in workflow folder

[ccha...@kinaxis.com]

After restarting jenkins (no jobs were running), my stage view disappeared.  When I go to the ajax page, I'm getting:

Caused by: java.lang.IllegalStateException: Could not load matching start node: java.io.IOException: java.util.concurrent.ExecutionException: java.io.FileNotFoundException: D:\build\Jenkins\jobs\MasterCI\builds\54\workflow\3.xml (The system cannot find the path specified)

The 3.xml file is in fact missing and is referenced by other xml files in the folder.  Any idea why this file would be missing?  Is it a bug in workflow?

Thanks,

Clint
