Great game but annoying minor issues

I enjoy the game a lot Microsoft has done a great job keeping the game strong but there are light glitches when one would log off and onto a map with weird areas with lighting, also if you were to leave your map and go back in your inventory is moved around and some items are missing, which is rather very annoying for the effort put into certain items, please fix this for its the only issue in the game
