Floors generated with R.I/GH - crashing model

Hi all,
We’re testing out using R.I to generate floors from CAD layouts depicting their boundaries. At the end of the process, we noticed “thickness” is available for editing as an instance parameter (in spite of it being determined by “structure” etc.). We then tried to edit this and were able to… momentarily. The Revit model crashed promptly after actuating the edits. .
Has anyone else seen this? Is this maybe (somewhat?) expected behavior? Or maybe there’s an issue with our workflow?
Thanks for all input on this.

Can you provide a small sample of your workflow? screenshoot even.

I take it you are bringing in the Autocad to Rhino first?

These are being done by the Add Floor component?? Floor Thickness is typically by Type. Is this a standard Arch Template project?
