Why Lucraft: Core ID Extender Matters for Big Superpower Modpacks
If you stack Lucraft: Core with several addon packs that register huge lists of superpowers, you have probably seen the kind of crash that ruins a good session. The original framework caps how many superpower IDs addon packs can safely register. Once you cross that ceiling, the game can bail out with errors that reference invalid IDs and exceeded ranges. Lucraft: Core ID Extender exists to lift that ceiling so ambitious packs can breathe.
What the mod actually does
Lucraft: Core ID Extender is a small compatibility utility built for Lucraft: Core. It uses Mixins to widen the internal ID table superpowers use when addon packs register new abilities. Out of the box it pushes the default upper bound to eight thousand one hundred ninety-two slots, and you can tune that number in config if your pack author or server admin wants a different ceiling.
Think of it as widening a parking garage before you invite every superhero-themed car on the block. Without the extra space, the game still tries to assign spots, hits a hard limit, and you get the infamous invalid ID and maximum range exceeded style failures once you pass the old cap (commonly cited around five hundred twelve powers in heavy addon setups).
Symptoms you might recognize
- Sudden crashes after adding another superpower-focused addon pack to an already large list
- Error messages mentioning invalid superpower IDs or maximum ID range
- Packs that work alone but break together because the combined registration count crosses the built-in limit
- World load failures that only appear once your mod folder grows, not on fresh instances with fewer addons
Those patterns usually point to ID exhaustion rather than a broken individual addon. The extender does not add gameplay content; it adjusts infrastructure so the core mod and its packs can coexist.
Dependencies and expectations
This add-on is not standalone. It requires Lucraft: Core by Lucraft. Load order and versioning still matter, because Mixins patch internal behavior. Always match the extender build to the Minecraft and Lucraft versions your pack targets, and back up saves before reshuffling a live world.
Server operators should drop the same files on the client and the server so both sides agree on registry size and config values. If a hosting panel strips optional config files, recreate the extender settings there so the raised limit applies everywhere.
Configuration notes
The headline feature is the new default cap at eight thousand one hundred ninety-two registrations, but the config is the control room. Some ultralight packs can leave defaults untouched, while megapacks compiling dozens of superpower lines might raise or double-check the value with their maintainer docs. Treat the number as a balance between headroom and memory pressure: more registered powers mean more bookkeeping, so do not crank values blindly without testing on your hardware profile.
When you are juggling many Lucraft adjacent jars, a tidy launcher workflow saves hours. If you want a friction-free setup pass, this kind of support mod can be folded into your instance with minimal fuss through the foxygame.net launcher, a flexible modern Minecraft launcher that lets you pull mods from the menu without hunting scattered pages. Pair that convenience with a quick in-game smoke test after every dependency bump.
Troubleshooting and reporting
Start by confirming Lucraft: Core itself loads, that every addon targets the same major version of Minecraft, and that no duplicate Lucraft core jars sneaked into the mods folder. Export the latest log after a crash and compare the stack trace to ID-related lines before opening a ticket.
If something still misbehaves even with the extender present, use the official issue tracker tied to the project so maintainers can reproduce your mix of mods, forge or loader build, and config numbers.
Who should use it
- Modpack authors bundling multiple Lucraft superpower expansions
- Players who love curated hero-themed lists and refuse to trim addons
- Private server communities running layered content seasons with rotating powers
- Anyone who hit registry crashes after crossing the old superpower threshold
Conclusion
Lucraft: Core ID Extender is the low-profile fix that keeps towering superhero mod stacks stable. It respects the creative scope Lucraft packs promise by stretching the ID budget with Mixins, offers a sensible default that fits most megapacks, and leaves finer control in config for cautious tweakers. Pair it with a matched Lucraft: Core build, verify both ends of a multiplayer setup, and enjoy hero mechanics without the ceiling crash that used to cap your imagination.
