CHECK THESE EVERY TIME

1. End from high up
- The fog/cloud layer should start a little higher than before.
- Look under island edges and pillars.

2. End from mid height
- The fog should look stronger and more noticeable.

3. End while flying downward
- The fog should build faster as you go down.

4. End surface
- The top of the island should still stay readable.

5. Nether / Overworld quick check
- Make sure those did not get worse.
