Ultimate FixesTools
NeoForge 1.21.1 · Server-side only · No client required
A server-side utility mod that acts as your server's all-in-one fire repair system, lag analyzer, and diagnostics toolkit. Built for vanilla NeoForge servers and hybrid setups like Arclight.
Fire fix system
→Hooks into BlockFadeEvent and neighbor notifications to catch cancellations instantly. →Captures a filtered stacktrace exposing the exact mod or plugin responsible. →Restores fire on the next tick if removed within 1–2 ticks — up to maxFireRestoreAttempts retries. →Avoids infinite loops: logs a permanent block warning after max attempts and stops. →Optionally ignores player-caused events to reduce false positives.Lag analyzer
→Rolling 100-tick history — real MSPT average and TPS, measured tick-by-tick. →Flags chunks with 50+ entity clusters and logs their coordinates and dimension. →Configurable MSPT threshold — only logs when things actually matter. →CPU and RAM stats accessible via command at any time.Logging system
All data written asynchronously (no tick overhead) to NadienFixesTools/ in your server root.
firelogs.logIGNITE_CANCELLED, FIRE_REMOVED, FIRE_RESTORED with timestamps and cause. rutas.logFull class path of the detected culprit, labeled MOD / PLUGIN / SYSTEM. quetolagea.logLag events with coordinates, dimension, MSPT, and entity counts.Built-in spam filter: repeated messages are suppressed after a configurable threshold.
Commands
**/nftps**
Live TPS, average MSPT, last tick time, server health status. *(Requires OP)*
**/nfresources**
CPU usage, RAM (used/total/max), entity count, loaded chunks, MSPT. *(Requires OP)*
**/nflagManual**
Manual lag scan across all dimensions, results saved to `quetolagea.log`. *(Requires OP)*
**/nfuptime**
Server uptime in hours, minutes, and seconds. *(All players)*
**/nflagchunk [top]**
Scans all worlds and lists the most problematic chunks with detailed info:
* Exact chunk coordinates
* Region file (r.X.Z.mca)
* Dimension
* Players present
* Entities with type and count (e.g. zombie x48)
* TileEntities
* Estimated TPS impact
Use `/nflagchunk 10` to show the top worst chunks.
Saved to `quetolagea.log`. *(Requires OP)*
**/nfkilllaged entities <radius>**
Removes all non-player entities within the given radius *(max 256 blocks)*.
Logs what was removed, amount, types, and coordinates. *(Requires OP)*
**/nfkilllaged tileentities <radius>**
Removes TileEntities (chests, furnaces, spawners, mod machines, etc.) and replaces them with air.
Useful for removing corrupted or crash-causing blocks. *(Requires OP)*
