Nodes missing

My co-worker installed Dynamo 2.0 and got these strange graphics. Would this be a conflicting add-in. I feel like I’ve seen this issue on the form before, but I couldn’t find it in the search.

Thanks.

Often a conflicting addin. Check what you have and let us know which one it is. Revit Python shell and NBS plugin are two I vaguely recall.

Thanks Jacob. We will take a look.
