The bug
When the /locate biome
command is used on a biome like the modified jungle edge (in my world with seed -2212060853571448367
, for example, but for most other seeds as well) where that biome is nonexistent for at least many thousands of blocks, the command will cause significant amounts of server lag.
To reproduce
Create a world with seed
-2212060853571448367
/locate biome minecraft:mushroom_fields
→ ❌ Notice that blocks don't drop and the game doesn't react

Affects 1.17.1 Pre-release 1.

Can confirm in 1.17.1 Release Candidate 1.
This and MC-250276 are actually the same issue. Considering that one has higher priority and goes deeper into the issue (as well as having affected versions up to date), I'd suggest making that one the main report.
Affects 1.17.
