What are deranged noises?

Deranged noises refer to noise values out of defined ranges. For example, the PV(peaks and valleys) level is defined only when the weirdness noise is between -1.0 and 1.0. If the weirdness noise is out of ±1.0 at a location, then I say there's a deranged weirdness noise at the location.
https://minecraft.fandom.com/wiki/Biome#Generation documents noises for biome generation and their ranges detailedly.
In both JE and BE, deranged weirdness causes deranged terrain height, which often results in interesting terrain and do not affect gaming.

What Happened?

In Bedrock Edition, deranged noises affect not only terrain height, but also structure generation. Structures may generated in wrong biome if a location has deranged noises.

• There's a big basin filled with water, which is caused by deranged weirdness value. In this basin, there're only two biomes: plains and meadow, but there're five structures gathering together: Pillager Outpost, Woodland Mansion, Village, Woodland Mansion, Stronghold. They all generate in wrong biome.

• There's a big basin filled with water, which is caused by deranged weirdness value. In this basin, there're six structures gathering together: Pillager Outpost, Woodland Mansion, Village, Buried Treasure, Woodland Mansion, Stronghold. They all generate in wrong biome.

Analysis

Game developers maybe do not know the range of the noises and assumed that they are all within ±1. As a result, when the game checks the biome to generate a structure, it often makes mistakes.
