I started a single player minecraft world then opened it to LAN in order to play with my brother. i got a whole bunch of wood and coal but then i had to leave for a couple seconds so i saved an quit. but when i logged back in i randomly started at spawn without any of the items that i had gotten when i played previously, even though i chose the save and exit option. Has anybody else had this issue and if so how can i prevent it occurring in the future?
