When launching an existing save, everything in my inventory disappears and i spawn with a brand new locator map, at first i assumed that it was an issue with the seed but it is happening on every save i've tried so far.

Nothing else in the saves is abnormal other than my ender chest also being completely empty, i've signed in and out of my xbox account multiple times and the issue still persists. (p.s i only have one account so it's not as if i signed in with another account)
