Chamber Fix
by uuc-dev-yuki
Chamber Fix corrects how Trial Chambers vaults reset and track cooldowns, so rewarded players are managed as intended.
What it does
Trial Chambers vaults hand out rewards on a cooldown, and the vault block entity keeps the state of which players were rewarded. Chamber Fix repairs the reset and cooldown behavior of these vaults so that the rewarded player state is handled correctly after a reset.
The fix targets Minecraft 1.21.11 on Fabric and runs on the server, so players join without installing anything. Server owners can adjust the reset time and clear cooldowns manually through admin commands. Time values accept the suffixes t, s, m, h and d, and seconds are the default unit when none is given. Commands require OP level 4 or the chamberfix.admin permission, which works through the Fabric Permissions API when it is present. Chamber Fix is released under All rights reserved and is not open source. Files are published for Fabric.

Time unit suffixes
Durations accept t, s, m, h and d suffixes, with seconds as the default unit when no suffix is written.

Use cases
Who it’s for: Server owners and operators who run Minecraft 1.21.11 with Fabric and want Trial Chambers vaults to reset and track rewarded players correctly. Players who only join a server do not need the mod.
How it compares
No Heavy Core Vault is a Fabric server-side mod for 1.21.11 under the MIT License, and it is not open source, so its source is not published for changes. Trial Spawner Retrigger is also server-side for 1.21.11 on Fabric, released under All rights reserved, the same license as Chamber Fix. Chamber Fix therefore differs from No Heavy Core Vault mainly in its license, while all three target the same single version.
