Missing nodes

Just found out that I’m not the only one with this problem:

Nodes and Wires Missing When Opening DYN File

The graph appears fine - the revit nodes within it are not being loaded correctly for some reason. (the graph itself is not corrupted so your data is not lost). Please try the steps advised above. remove all packages remove all third party addins look in the notification menu for notifications (green circle in dynamo menu near help menu) try opening this file on another machine.
