CERBON'S Better Beacons Fix
by Panzimy
CERBON'S Better Beacons Fix is a NeoForge utility that stops a lag problem in CERBON'S Better Beacons on 1.21.1, where the corrundum cluster color was checked on every tick.
What it does
The fix changes how the corrundum cluster color is handled. In the original behavior, Better Beacons tried to load the color on every game tick, which caused large lag spikes during play. The fix replaces that check, so the color system no longer runs each tick and the game experience stays smooth on servers that run the beacon mod.
The mod is server-side only: players join without installing anything, and only the server needs the fix. It requires CERBON's Better Beacons and Quark, and it is built for 1.21.1 only. Its license is the MIT License, and the code is open source, with a public source repository and issue tracker for reports.
Installation is simple: place the file in the mods folder of the server and start the game. The first release, 1.0.0 for 1.21.1, was published on 2026-06-08 and last updated on 2026-06-11.

What the author says
This mod fixes lag and an issue with Quark and CERBON's Better Beacons, because in 1.21.1 Quark has changed color system for the currundum cluster. And because Better Beacons are trying to load the color every tick your game can experience really big lag spikes, I will try to send a PR to fix this, but for now this…
