Fix a link

2025-05-04T19:54:12Z

‎Sources of noise: Updated, apparently much simplified, noise system in later versions.

2025-05-04T19:39:06Z

Add a section on noise meter, remove diagrams. If we're never going to update them, we're better off without them.

‎Player shouts: Update to 0.33

2025-05-04T18:39:54Z

‎Ambient noise: Update, remove unnecessary table.

+This effect is significant but not drastic. Shouts will not travel far in loud branches, whereas usually minor noises, such as attacking, may be sufficient to attract monsters in quiet branches.
