SpotElevation.ByFloorPlanAndPoint crashing in Automatic mode

1

Hi

I am using Clockwork’s ‘SpotElevation.ByFloorPlanAndPoint’ node to add a spot elevation to a stair landing. It runs fine in Manual mode but when I switch to Automatic model is crashes Revit and Dynamo. I’m using Revit 2018, Dynamo 1.3.3, and Clockwork v1.31.1.

This is the Python script within the node. Is there any reason it would be causing it to crash? @Andreas_Dieckmann
