Bug with Operational Entities Emptied out - Save issues

Hello all,

I have had some issues with Capella recently. For whatever reason, it sometimes will clear my Operational entities diagram out completely. This is the 2nd time this has occurred.

Additionally, the most recent time it had another error where it also cleared out the involvements in my operational capabilities diagram. This occured when I saved the file and re-opened it, and it doesn’t seem to revert back to how it was earlier.

Any ideas as to why this might occur and what could be done to prevent this? The document has been saved on Google drive for cross-collaboration, would it be better to save the document locally?

If multiple versions are saved, I could possibly recover an earlier version and get back some of my work, but I’m not sure if Capella is capable of that.

Any help would be much appreciated!

Regards,
Mahdi K
