Phone died mid game Chests Glitched and more missing items

My phone died mid game when I came back to my world the chests disappeared and was only able to see the outlines when trying to break the invisible chest it only gave me a chest with nothing else the signs on my chest were also glitched and invisible and was also no longer able to open dispensers The signs on my chests were also invisible and when I broke the sign it gave me a weird block.
