The 2026.02.17 server update changed the signature of AssetModule.registerPack from 3 to 4 parameters, breaking any mod compiled against the old version (e.g. AdminPortals).
This is a Hyxin mixin earlyplugin that re-adds the old 3-argument overload so those mods keep working without needing a rebuild.
// old (before 2026.02.17)
registerPack(String name, Path path, PluginManifest manifest)
// new (2026.02.17+)
registerPack(String name, Path path, PluginManifest manifest, boolean flag)
The mixin adds the old method back and delegates to the new one with false as the default.
