We face an irregular issue with only one user :
in the local cache folder we should see all lid... and sid... files along with the subfolders per existing workspace. For some reason, one user frequently mentioned that all the saved work in any workspace other than the active workspace were lost. Afte a few occurences we found that overnight, the lid... and sid... files were still there but the actual subfolders who described the workspace content etc... were deleted. This operation left the CAD files that were still there useless however. After activating each workspace, the subfolders were re-created, but the link with the lid... files was not restored, which is infortunate but seems logic since no other system could have had has any information of the new files in that workspace.
We could simulate this situation by manually deleting (or renaming) one of these folders. They are also created when activating the workspace and the locally modified or new files are no longer in the workspace.
What we learned today : the situations seems to be happening only on a Friday...
The option to save and upload automatically is not really helpful since that eliminates our possibility to rename in the modeltree after copying.
We are running Windchill 10.1 M050 (planning to upgrade within 6 months however) and Creo 3.0 M090, but have seen this issue on previous Creo datecodes as well.
I have provided this user with another Windchill account, but the problem still occurs.
