Bumps Minecraft version from 1.21.8 to 1.21.9 on the snapshot 25w37a! This is not a stable release.
The only major code change was in the handling of armor rendering.
Known Issues:
- Bow guards that have an active target have a tendency to take paths that incur fall damage when no other path is available.
- Melee guards with shields can get stuck in a permanent blocking-only loop when 1v1 against a ranged mob.
Migrating from <=1.21.5: you will see warnings in the logs like Failed to decode value '{}' from field 'ArmorItems' at index 0': No key id in MapLike[{}]. This is due to inventory management changes and is expected. May fix in the future.
NOTE: attached file doesn't match recent change to version naming convention. Snapshot now comes directly after MC version number and is followed by mod version number.
