Question: MagicGrid - Collaboration Center

Hello,

I uploaded a local MagicGrid project to our new Collaboration center.

That worked fine and I am able to see all diagrams in the web-ui and can edit them.

Today I realized that the project in Magic Cyber System lost all MagicGrid Containment Diagrams.

Even the Main MagicGrid "index landing-page" got lost.

What have I done wrong and is there a way to recover the MagicGrid?

Thank you
