Played on my world for a few hours, exited and saved game to switch to another xbox in another room. Synced game, loaded, and found that the building i was working on was merged with original save from when i started playing. My inventory and some chests were reverted back to earlier save but other chests kept newer inventory.

Exited and saved game. Switched back to original xbox, synced, and loaded and ended up with huge chunck of world disappeared. Thinking it loading in walked over it and fell into void killing me.

Not sure if this is a bug or if i have a corrupted save. Just thought i would report in case.
