Problem

Pre-existing players missing backpacks after migrating server without Minepacks from snapshot version 20w07a to server with Minepacks running Latest Release 1.15.2.

What I have tried

I reloaded the playerdata on the world files and that corrected the issue for most players, but some are still without a backpack. I have also tried reloading, and restarting the backpack for the affected players with no change, as well as backup and restore, open via command, having the player open via command, and cleaning the backpack. All of these actions have yielded no results for the affected users. Please assist.

Resolution Notes:
Issue corrected by server reboot after deleting users' player data. No further action required. Closing ticket.
