I was looking for a new world seed to start a new map for gameplay, but when creating two different worlds I noticed several world generation errors with the character being able to appear underwater, structures not well positioned, two chests in the same structure, pieces of the world floating and the water with error in physics.

Note: Unfortunately I do not have the coordinates of the errors witnessed, except for the double chest error that was used in the second seed with its coordinates in the image.
