A lightweight mod-optimizer for FTB Quests. Removes micro-freezes when moving items and turning in quests, makes inventory checking smarter and quieter for the server - without changing the gameplay and quest rules.

Main features

• Smart inventory detection - heavy scans are launched only when really needed.
• Debounce checks - a series of events are added up to one delayed check (less load spikes).
• Ignore NBT noise - changes like charge/durability do not trigger unnecessary checks.
• Fast resource turn-in - item withdrawal in one pass and one progress update.
• Icon cache (client) - smoother quest book and tips.

Settings (snbt)

• detect.debounce - enable debounce.
• detect.delay_override — override check delay (tick), -1 = like in FTBQ.
• detect.ignore_nbt_only_changes — ignore "same item + quantity".
• consume.aggregate — aggregated resource delivery.
• consume.max_slots_per_pass — limit of scanned slots per pass.

Compatibility

• Does not change gameplay/progress, safe for current worlds.
• Works in singleplayer and on servers.
• Recommended on server (biggest effect). Client is optional for UI cache.
• NeoForge 1.21.1+, requires FTB Quests installed.

Why install?

• Less lag when managing inventory.
• More stable TPS on large bases.
• Smoother quest interface.

Just install the mod — it will do the rest itself.

If you want better performance, install my second mod, both mods will practically eliminate the lag problems associated with achievements and quests.
