I created a Nintex Form and had published it. Then I created a content type and added it to my list. Afterwards the Nintex Form was reset and I lost my customizations/form template that had been built. Is there a way to retrieve it? Is there a better way to approach this in the future to avoid losing customizations? Why did the form get reset?
The best way is to export the customized forms and stores it locally or in a repository (TFS/GIT ...). If something happens, you can import the latest version.
The second option is to restore from the version history:
Clck on "View version history"
Select the right version
