I’ve created most of my Dynamo scripts in Revit 2019 using Dynamo 2.0.3. I’ve got Revit 2020 installed with Dynamo 2.3.0, and when I open any .dyn files in Revit 2020, several core nodes are missing. I created a simple example showing the script created in 2019, and what it looks like in 2020. The “List Create” node is missing in 2020, and I get the errors below in the log. The “String.Concat” remains so this is only happening with certain nodes.
