Using a LAN with main run from Windows 10 PC. 2 other users connect via XboxOne on LAN.

Can connect and player without issue. Xboxone players log of first using save and quit, then PC player logs off. When logging back on, the Xboxone players have lost all items that were in inventory!

This has happen 8 out of 10 loggins. Tried with PC remaining on, and the Xboxone player leaving and entering, then with all players off. The PC player has no issues with inventory.

This kind of makes LAN multiplayer unplayable unless the all items are placed in chest before logoff.
