Nodes collapsing on save to a new Dynamo?

Hello, I opened an older script in Revit 2021, then saved it as a new name.

I closed it and reopened it and it came out with all nodes overlapping.

(Cant upload image right now, fore some reason.)

Is this a known issue when opening older scripts in Dynamo 2.0?

thanks.

Usually (95% of the time) this is a conflicting Revit add-in. Disable your Revit add-ins and see if it persists.

Thank you Jacob,
in this case, I re-installed several packages to the latest version, and it seems to be opening properly, no more overlapping…

regards
