Anyone else getting these?
I'm getting them like crazy this morning, and unfortunately after clicking Close the webpage never gets past "Building workflow." I end up losing all of my work since the last Save/Publish.
I believe a tech in the Nintex support team told me these can be generated when the Nintex service is having issues--this could explain it. I went all day yesterday configuring 50-75 actions in a workflow and I've received it already 7 times this morning configuring less than 20. Quite the time waster.
