"max" is ordered before "min" by the JSON data generator

Some worldgen datapacks can kill the internal server (possibly related to density functions)

Explorer maps leading to custom structures can cause the server to hang

Worldgen datapacks affecting the dimension on dedicated servers don't register at first launch

Spore blossoms, cave vines, and pointed dripstones generate indented into the cave surface

Dimensions with a multi_noise biome layout prevent worlds from being upgraded from 1.17 to 1.18

Feature placement doesn't check for biomes, causing unnecessary lag

Terrain shaper in noise_settings is not used

random_patch features are now forced to be square instead of rectangular

Custom dimensions cannot be generated without a set seed field

vegetation_patch features from datapacks can cause a crash by IllegalStateException

World-gen datapacks can cause crashes when first generating world

large_dripstone's wind is heavily biased towards the northwest

Generation of geodes with high noise multiplier can kill the lighting engine

Amethyst geodes can overwrite bedrock

A geode configured_feature causes a crash when use_alternate_layer0_chance is used with no entries in inner_placements

In custom dimensions, terrain generation is based on the predefined seed, but structure generation is affected by the world seed

Certain worlds render biome fog darker than intended

Crash when using a non-mushroom block in a huge mushroom feature's cap

"netherrack_replace_blobs" of large size can cause inconsistent generation

Custom world generation or dimensions from data packs don't work in Java Realms

Certain dimensions can cause a game crash
