Neo Origins

NeoOrigins 2.0.3 — server boot fix + datapack auto-merge

Critical patch for anyone running NeoOrigins on a dedicated server: 2.0.0, 2.0.1, and 2.0.2 all crash at boot before the world loads. 2.0.3 fixes that. Also includes a quality-of-life change for datapack authors so origin packs no longer create a separate picker screen.

EntityMakeStuckInBlockMixin (a common mixin for cobweb-affinity) contained an instanceof LocalPlayer check. Mixin resolves type references at transform time, and LocalPlayer.class isn't on the dedicated-server distribution — every server bricks at boot with ClassMetadataNotFoundException. Singleplayer was unaffected because the integrated server runs on the client distribution where LocalPlayer exists.

Fix: trampoline the LocalPlayer reference through a new ClientStuckInBlockHelper class. The mixin calls a static method on the helper only inside level().isClientSide(); the helper class is loaded lazily and only ever on the physical client. Server JVM never resolves LocalPlayer.

Datapacks that ship their own e.g. erin:origin layer (the most common Apoli/Origins-style structure) were creating a separate picker screen alongside the main NeoOrigins origin tab. New mergeForeignSamePathLayers pass folds any layer whose path is origin or class into the canonical destination (origins:origin or neoorigins:class respectively).

Pack authors who genuinely want a separate picker tab opt out via "standalone": true on their layer JSON. INFO-level log line announces each fold so debugging is straightforward:

Folded foreign layer erin:origin (7 origins) into origins:origin

Carried over from 2.0.2: the [sun_damage] block in neoorigins-common.toml exposes helmet_dura_damage_chance (default 0.07, range 0–1). Live-read each evaluation, so server admins can tune helmet wear without restarting.

If you maintain a dedicated server running NeoOrigins, update immediately. There is no workaround for the 2.0.0–2.0.2 boot crash short of removing the mod or running on the integrated server.
