Dynamo nodes clear/missing

Using latest Dynamo 2.0 and Revit 2017.2. My nodes are missing… I am at a loss here…

Two things to check.

  1. Remove all Revit add-ins This can be due to a dependency conflict which is created by an out of step add-in.

  2. Remove your library view extension or Remove all packages from your library This can also be triggered by a bug that creates a race condition within the Dynamo library. I’ve had success resolving his limiting packages to ones without dependencies and pre-formatted for 2.0. It should be resolved in an update in the near future.
