Lately a collegue of mine noticed that randomly his nodes would disappear upon opening a dynamo graph from Civil 3D. I thought he was crazy until I just experienced it myself. I created the graph, ran it with Dynamo window still open. Saved it and closed out. Tried to run it using the “Run Script” command inside C3D and nothing happened. Opened back up my graph to find one of my nodes no longer on the screen - as if I never even placed the node!
Please help me figure out what is happening or the fix! I’m teaching a hands on lab at AU and IF this happens, want to be able to convey the reasoning and fix.
