TheFastLaunch v1.9.1 - Compatibility & Performance Hotfix
🚀 TheFastLaunch v1.9.1 (Consolidated Hotfix Release)
This release consolidates critical compatibility fixes and performance optimizations addressing recent reports and issues:
🛡️ 1. PathPackResources "Invalid path ''" Error Spam Elimination
- Ultra-Fast Resource Check: Replaced recursive
pack.listResources(..., "")calls withhasThingsResourcesdirect directory/ZIP existence inspection (completes in <0.5ms across all 392 packs). - Forge PathPackResources Fix Mixin: Added
FastLaunchPathPackResourcesFixMixin&FastLaunchVanillaPathPackResourcesFixMixinto safely intercept and cancel empty path resource lookups beforeFileUtil.decomposePathfails. - Complete Eradication of 190,000+ Error Logs: Completely wiped out the 193,578
[Render thread/ERROR] [net.minecraftforge.resource.PathPackResources/]: Invalid path : Invalid path ''log spam that previously caused 200MB+ log inflation and a 2-second startup hitch.
🛡️ 2. Forgery / Fabrication Compatibility (Fixes #4)
- Dynamic Forgery Detection: Added automatic detection for Forgery / Fabrication mods via classloader and filesystem probes.
- Mixin & Preload Bypass: Safely bypasses early entity preloading and potentially conflicting mixins when Forgery is active, preventing fatal
MixinEntityinjection failures.
🐛 3. ModernFix Compatibility & Async Error Logging (Fixes #5)
- Fixed ModelBakery ClassCastException: Resolved a conflict where ModernFix's
DynamicBakedModelProviderwas overwritten byCollections.synchronizedMap, safely protecting specialized concurrent map implementations. - Asynchronous Error Logging: Attached an error trapping listener (
whenComplete) toModelManager.reloadto properly output full stack traces rather than causing silent barrier lockups. - Worker Pool Optimization: Restored clean background thread execution for resource reloading while preserving multi-core parallel baking on
FastLaunch Quiet Worker Pool.
⚡ 4. Robust Multi-Core MBD2 Parallel NBT Loader
- High-Performance Multithreaded Loading: Parallelizes NBT parsing across
ForkJoinPoolfor heavy multiblock definitions (including massive 160MB+ files such assfr.mb). - Hybrid NBT Binary Decoder: Uses
NbtIo.read(uncompressed NBT) natively with automatic graceful fallback toNbtIo.readCompressed, ensuring 100% data integrity with zero parse dropouts. - Full Recursive Directory Walk: Fully traverses subdirectories using
Files.walkFileTreeidentical to MBD2's native structure. - Deterministic Thread-Safe Registration: Decodes heavy NBT bytes in parallel across all CPU cores, then sequentially dispatches definitions on the caller thread to eliminate race conditions on non-thread-safe consumers.

TheFastLaunch v-b1.8.1 - Complete Multiplayer Registry Synchronization Fix (Tinkers' Katanas)
🚀 TheFastLaunch v-b1.8.1 Release Notes
⚔️ Complete Multiplayer Registry Synchronization Fix (Tinkers' Katanas & Json Things)
- Root Cause Resolved: In multi-core parallel parsing of JsonThings thingpacks, calling
parseFromElementconcurrently resulted in an unsynchronized data race onThingParser.builders(ArrayList.add()). This caused items (specificallytinkers_katanas:fuma_shuriken) to be dropped from the registration list, leading toMissing registry data for impl connection: minecraft:item: tinkers_katanas:fuma_shurikenand immediate server disconnects during the FML handshake. - Full Deterministic Synchronization:
FastLaunchThingParserParallelMixinnow parses items viaprocessThingon parallel worker threads without writing to the sharedbuilderslist.- On completion, both
buildersByName(Map) andbuilders(List) are sequentially and deterministically populated in exact key sequence order. - When Forge executes
ItemParser.register(), 100% of defined items (bothkatanaandfuma_shuriken) are registered with identical IDs matching the server.
- GameData Logger Isolation:
- Renamed internal Mixin logger in
LoadRegistriesParallelDispatcherMixinto prevent accidental shadow/overwrite of Forge'sGameData.LOGGER.
- Renamed internal Mixin logger in
🌐 Pure Client-Side Operation
- Continues full client-side multiplayer support (
DisplayTest.IGNORESERVERONLY) requiring zero modifications or installation on the server side.
TheFastLaunch v-b1.8 - Multiplayer Server Independence & Addon Tool Compatibility
🚀 TheFastLaunch v-b1.8 Release Notes
🌐 Multiplayer Server Independence (Pure Client-Side Operation)
- Zero Server Setup Required: TFL now natively declares
DisplayTest.IGNORESERVERONLYin bothFastLaunchForgeModandmods.toml. - You can now freely connect to any external multiplayer server (friend servers, public servers) with TFL installed only on your client without being rejected by Forge mod handshake checks!
⚔️ Tinkers' Katanas & Json Things Addons Full Compatibility
- Deterministic ThingParser Order: Parallelized JSON parsing now strictly aggregates into the main registry builder map using the exact deterministic key sequence. This completely eliminates internal Raw ID / Registry Desync when playing on multiplayer servers!
- Tinkers' Addon Weapon Protection:
FastLaunchTinkersJeiPrefilterMixinnow fully preserves addon tool items (such astinkers_katanasKatanas and Fuma Shurikens) in the JEI index while continuing to compress vanilla Tinkers' massive NBT variants.
🛡️ Robust Server-Safe Guard
- Client-only UI event handlers (TitleScreen update notifications) are now strictly guarded by
FMLEnvironment.dist.isClient().
