When i join my world the game would crash everytime the saving chest icon showed up. When i got it to stop crashing, the signs on my barrels were not rendering but you could still see the hitbox, the same happened to my ender chest. Once i mined my ender chest and placed it back it was fine. I couldn't open any of the barrels, and when i broke them none of them items i had inside popped out (so i lost everything i had inside them) when i broke the signs on the barrels they dropped the item thats called 'tile.wall_sign.name'. I then placed  the item and it placed a sign but I couldn't write on the sign and its hitbox was a full block, once i broke it and replaced it the signs worked again. The video shows the bug with the barrels (that barrel should've had dirt in it.).

P.S i hoped that all made sense
