Loading game bug

[SgtMassacre]

Hey there, whenever I load any of my save files the game puts me in the same spot on the map and reverts my inventory to a previous state, losing my items. The world doesn't seem to change back and it does this no matter which save I load, solo or multiplayer. I'm on Xbox and I just got the treasure chest in the sandbox open with the instructions for the mace before this all started. Any advice would be appreciated, thank you.
