I had already successfully conversion-migrated to version-4 back in March 13th;
all my saved sessions converted into "Collections" and even "snapshots" survived the transition.
On 28th (UTC+2) the Session Buddy stealth-updated during a Chrome a session.
And now everything saved prior and after March 13th is now gone;
only the snapshot at March 28th 3:43PM / 15.43 and two collections saved since are remaining.
Also the oldest manual-backup-file I had created was done with Version-3 on January 2024.
Worth noting during all this updating, there was some "pagefile / virtual-memory"-bloating happening in the background which did temporarily did top-up my (permanent-physical) storage-space.
I am however doubtful there is any "corruption" or anything similar happening since nothing else on my storage-space is missing;
only the Session-Buddy-collections prior version-4.0.2 are not displayed on the Session Buddy-GUI.
Considering the pre-version-4 data-file is still intact and was previously successfully migrated, I am assuming version-4 also has its own data-file;
is it possible the import this from somewhere to restore all the data prior version-4.0.2?
