So I have  put about 20+ hours into this save and am really enjoying the game so far, with a big project underway I decided to hop on a boat and go to a desert island and get some sand. Suddenly, chunks start to not load and im floating my boat in nothing, I reload and find myself where I should be in the world and hop out of my boat

I tried to dig but nothing was being dug, the animation and effects played but no terrain moved. I Reload The dirt I dug is now missing from the ground and in my inventory but the same bug persists. My inventory also doesnt update and my hotbar is empty   Animals move on the spot, my boats wont turn and any action I take (for example opening my map) happens the second I exit the game.

Any suggestions to fix this? Ive poured hours into this save and it would break me up to lose it
