MISSING BEAMS AND NODES IN MODEL WHEN REOPENING FILE OR EDITING IN STAAD EDITOR | STAAD.PRO CONNECT

Hi!

I have this problem with the STAAD File missing elements when I save the model and reopen it later.

This shows up when I open the file, and clicking Yes shows the warnings about the "Beams #123 is not found in the structure, removed from the list."

Auto-recovery files for the model show the same issue.

A similar thing happened when I tried to finish the analysis without closing STAAD.Pro (without closing the saved file), when I open and edit load designation in Staad Editor elements go missing.

Is there anyone who knows a fix for this? Or experienced the same?

Thank you in advance!
