Echo Protocol 0.5.0-beta.2 — Hotfix 1

This build contains a major cross-version stability and visual regression fix for Echo Protocol.

Fixed Echoes sometimes using the default Steve skin instead of the target player's real skin.
Fixed player skin data not being correctly propagated into the modern render state on newer Minecraft versions.
Fixed fallback skins potentially remaining cached instead of updating to the real player skin.
Fixed Echoes appearing fully opaque instead of translucent on Minecraft 1.21.9–1.21.11.
Restored the intended ghost-like transparency, alpha and fade behavior.
Fixed Echo movement being able to pass through solid blocks in some situations.
Replaced unsafe movement behavior with collision-aware movement and swept-path validation.
Memory Echoes now safely stop and fade out when an old recorded route has become blocked by newly placed blocks.
Fixed The Original advancement being granted before The Original had actually manifested to the player.
Advancement progression now waits for the corresponding gameplay event to successfully occur.
Improved cleanup for failed or blocked Echo events.
Improved player skin caching and validation across supported Minecraft versions.
Fixed Minecraft 1.21.1 version metadata being too broad.

Every supported Minecraft version from 1.21.1 through 1.21.11 was re-tested using dedicated Prism Launcher instances.

Final production JARs were tested for:

52 automated tests also pass on the final builds.

This is a bug-fix release only.

There are no new gameplay features and the mod version remains 0.5.0-beta.2.

It is strongly recommended to replace older 0.5.0-beta.2 builds with this hotfix.
