Xbox offline/online save glitch.

So I've seen posts here and on reddit about save files for offline not saving player inventory correctly and after some playing around I figured out a work around. In your network settings change to offline mode and boot the game. Once in load your last correct save backup and depot your entire inventory (which should be the correct one) into a box that already existed within your base. Once you do that switch back to online mode and save the game. Quit out and reboot your console. Relaunch grounded and it should resync your game files. Load in the save and all your items should be in that box. Hope this helps.
