If the temporary directory /tmp/Flix* is removed while the Flix Server is running, the Flix Server will complain it is missing, rather than create a new one.
 
Customer reported version
6.3.2
 
Steps to reproduce
1) While the Server is running, remove the Flix* folder found in the Flix Server machine's /tmp directory.
2) Via the Client, import a panel to Flix.

Panel is created, thumbnail is broadcasted.
 
Actual behaviour
Panel is not created because the /tmp/Flix* directory does not exist.
