Never seem that before, are you the only designer anyone else possibly delete it?

Did you try an reload? I have sometimes the behavior, that while opening the workflow gallery was not loaded successfully and that shows like you described.

I have the same issue, but reloading the page didn't work for me.

Wow, that behavior I've observed that by my system yet.

Can you see the workflows by using the SharePoint designer ?

Just connect to the Site and click on Workflows, here you should see all your workflow on the Site-Collection plus the Workflows provided by Nintex.

Where you able to find out what happened? Can you provide a solution?

Nope, I already tried viewing it in SharePoint Designer with no luck.  It's a good thing I have a back up of it elsewhere, so I just recreated the workflow using a different workflow name.

But If you have to use a different workflow name, the old workflow should be still in place , even you couldn't see the workflow.

So I would contact the Nintex support, to help you.

PS: It is always a good idea to backup the workflows

Nintex Support has been contacted.  We only have Software Assurance support, so it may take a while

I also witnessed this behaviour some weeks ago. Workflows disappeared and never appeared again but I also had a backup :-)

Be patient, please hold the line

We have also just experienced this behaviour. Did anyone find out why this happened?
