Naturally-generated seagrass destroys ice
Upon world generation, sea grass can generate underwater. In doing so, it can delete any blocks of Ice that would otherwise be above it. This does not seem like intentional behaviour.
This can be fixed in two ways:
- Implement a new block that consists of sea grass being "fossilized" inside of ice
- Make ice override seagrass generation

These issues seem to have a different cause. Please close this report for now.
Currently, there are multiple categories of features in the game, such as lakes, vegetation and ores. They are all generated in a specific order that isn't very logical, causing various generation problems.
Some of the features expose blocks (lakes, structures and springs). To make sure certain ores are 100% hidden (debris, large diamond ore), they should generate after those features, at the point where no more air/water generates.
I'm suggesting a new order for the features, and the reasoning for it. I'm using the feature categories named here: https://minecraft.fandom.com/wiki/Biome/JSON_format. I omitted some categories that don't cause problems.
| Feature | Fixes |
|---|---|
| 1. Caves | |
| 2. Aquifers | |
3. LAKES * they generate pockets in the terrain, functioning like mini-caves
|
|
| 4. UNDERGROUND_STRUCTURES - geodes, fossils, dungeons | |
| 5. Structures | |
*features that generate liquids - springs (was in VEGETAL_DECORATION)
|
no more blocks are exposed after this| |
| 6. UNDERGROUND_ORES + UNDERGROUND_DECORATION - features that replace existing blocks: ores, stone blobs, soil disks |
|
| 7. TOP_LAYER_MODIFICATION - freezes water, adds snow on top |
|
8. VEGETAL_DECORATION - surface features that add trees + plant blocks
|
Note: some of the bugs listed may not be reproducible anymore, but they're still open.
Some examples of this new order being used:
- A lake is generated in a swamp, and then a hut is generated inside it. Seagrass and lily pads generate in the remaining space.
- A monument / shipwreck / jungle temple generates, then biome vegetation generates on top of it (kelp, vines etc.) - they don't need to add their own vegetation.
- A village generates paths, and plants can generate only in the remaining space.
Edit: vegetation already generated after structures.
