Ok,

Setup/scenario details: On a converted world the world is on my XBOX live account single player seems to run fine.

Here is the issue player 2 will login to the world and have all the gear and levels from the xbox edition save. player 2 will play from 1-3 hours give or take and after either logging out or the game crashing, upon logging back in player 2 will be a anywhere between 1-3 hour behind where they were. Meaning inventory/ levels have reverted. for example: player 2 had 100 level after the conversion and used the levels did some other stuff and about 1 hour later the game crashed after rebooting the Xbox and logging back into the world player 1 is right where they were when the game crashed but player 2 is back to 100 levels and inventory has reverted. I hope this make sense..

Thank you
