DAI 1.9.1

DAI 1.9.1 is a stability and runtime patch for DAI 1.9, focused primarily on live datapack reloading and custom experience/menu world handling.

Hot Reloading

• Added proper DAI datapack hot reloading.
• Updated server-side DAI definitions live when datapacks are reloaded.
• Updated client-side runtime definitions during the same reload cycle.
• Custom entity behavior and spawn definitions now adopt their reloaded definitions without requiring a restart.
• Reloaded actions, logics, menus, recognition definitions, reactions, recipes, and supported runtime definitions are refreshed live.
• Added validation during reload before updated definitions become active.
• Removed unnecessary restart requirements when changed content does not require native registry reconstruction.

Experiences & Custom Menus

• Fixed existing worlds not appearing correctly through DAI custom experience and title-screen menus.
• Improved discovery of worlds belonging to DAI experiences.
• Fixed custom menu handling for continuing and selecting existing experience worlds.
• Improved title-screen resolution between global experience menus and world-specific menus.
• Improved world/session transitions when using custom DAI title screens.

Fixes

• Improved runtime state handling when entering, leaving, or switching worlds.
• Fixed issues where custom DAI menus could retain stale world/session state.
• Improved synchronization between datapack reloads and the currently active DAI runtime.

Compatibility

• Retains the complete DAI 1.9 feature set.
• Existing DAI 1.9 datapacks remain compatible.
• No migration is required for datapacks that do not depend on the corrected runtime behavior.
