after running a script my Revit no longer has a Dynamo instance that I can undo? another user from a different office is seeing the same behavior.

Revit 2018.3 - Dynamo 2.0.1.0

Try to read the known issues in the readme file… This is a known issue in dyn 2.0, along with the copy paste and other shortcuts, use rightclick

Searching ‘‘2.0 delete’’ gives you this as the first hit:

> Since. i’ve installed Dynamo 2.0.1, I’m unable to delete nodes using the delete button. The only way I can delete nodes is right click and remove. Is this a known bug?
