FTB Quests Freeze Fix
by Txni
Players who open the quest book for the first time on a large modpack can hit a long freeze, and FTB Quests Freeze Fix moves that work to the loading screen.
What it does
The fix caches the quest menu during startup, while the game is still on its loading screen. The quest system needs Minecraft's Creative mode text search provider, which survival play never initializes. Building it means looping over every item, collecting its tooltip text and processing each entry, and the cost grows with the number of installed mods that add tooltip text.
The mod does not remove that cost; the cache has to exist for quests to work. It only changes when the cost is paid. In the author's tests on a role-playing modpack, opening the quest book the first time caused a lag spike of about 10 seconds, and with the cache built at startup that delay no longer happens during play. Loading takes a few extra seconds, scaled to how long the freeze would have lasted.
The mod is published for Fabric and Forge, and only the 1.20.1 game version has files. It is client-side only, so servers do not need it. The code is under a custom license and is not open source; source code and an issue tracker are public.
Key features
Startup caching
The quest menu data is built while the game is still loading, so the first open of the quest book does not stall.
Text search provider setup
The Creative mode text search provider that the quest system relies on is initialized ahead of time.
Adjustable load time
The extra time added to startup depends on how long the freeze would have lasted in that pack.

Use cases
Large modpacks
Packs with many items and quests, where the cache build takes longest, are the main case the mod targets.
Who it’s for: Players of large quest-based modpacks on 1.20.1 who see the game freeze during their first quest book open.
How it compares
Quests & Teams Fixes is also for 1.20.1 on Fabric and Forge, but it runs on client and server and is released under the MIT License. Better Quest Pop-up is client-side only and covers 1.12.2 – 1.20.1 under the GNU Lesser General Public License v2.1 only, so it targets a different problem entirely. Questlog Quest Book is a Forge-only, client-and-server mod for 1.20.1 – 1.20.6 under All rights reserved, and is not open source.
