Apugli Mixin Fixer

A mixin shim for Minecraft 1.20.1 (Fabric) that fixes the launch crash when Apugli 2.10.x runs with Origins 1.10.2 (Apoli 2.9.2).

Read this first. Apugli has been delisted from Modrinth and CurseForge and its repo is archived. There is no 1.21 build and there will not be one. This mod only helps if your pack already has Apugli 2.10.x sitting in mods/. If you are starting fresh, this is not for you.

The crash

Apugli's EntityConditionsMixin uses @Redirect to intercept EnchantmentHelper.getLevel() and EnchantmentHelper.getEquipmentLevel() inside Apoli's EntityConditions.lambda$register$47. In Apoli 2.9.2 those calls live in lambda$register$45.

Lambda numbers are compiler-generated and they move between Apoli versions, so the redirect finds 0 targets and takes the game down with it:

InjectionError: Critical injection failure: Redirector apugli$useModifiedEnchantmentLevelSum
in apugli.fabric.mixins.json:common.EntityConditionsMixin from mod apugli failed injection
check, (0/1) succeeded. Scanned 0 target(s).

What this does

• lambda$register$47 stays exactly as Apoli wrote it. getRootVehicle, net.minecraft.util.Pair, the real riding_root logic. Two enchantment calls sit in a branch that never runs, which is enough for Apugli's redirect to find its targets and the game to launch.
• The real enchantment calls in lambda$register$45 get redirected through Apugli's modify-enchantment-level power, so the enchantment entity condition respects sum and max.

Pinned

It checks versions and refuses to load on anything but:

• Minecraft 1.20.1
• Fabric Loader 0.14.0 or newer
• Origins 1.10.2+mc.1.20.x
• Apoli 2.9.2+mc.1.20.x (bundled in that Origins jar)
• Apugli 2.10.x

A crash about a missing lambda is better than a silent wrong condition.

4.0.2 is not safe to keep

If your pack uses riding_root, take 4.1.0. 4.0.2 stuffed live null calls into lambda$register$47, called getVehicle() and used the wrong Pair type, which rewrote riding_root into a different condition.

Status

Archived. Apugli is gone, so there is nothing upstream to fix. If you are moving to 1.21.1, this is not part of that path.

MIT. Mixin fix only, no game content.
