Icarus Fixes - January 31 2026 Update

Date: January 31, 2026

ICARUS, the PvE survival experience for up to eight players, receives a substantial patch that refines core gameplay loops, expands crafting options, and resolves a long list of bugs. The update focuses on quality‑of‑life improvements for resource handling, mount genetics, radiation mechanics, and more.

Key Gameplay Improvements

Deployable storage counted for crafting: Batteries, rain reservoirs and portable tanks now contribute directly to resource checks on crafting benches. Example - Pickled Carrots no longer require an active water pump if the linked storage is full.
Direct drinking from Tier‑3 water purifier: Players can now drink straight from the purifier; the interaction has been merged for rain‑reservoirs and water‑purifiers.
Inventory interaction overhaul: One‑stack items such as oxygen tanks and water‑skins can be dragged and swapped directly in survival slots, speeding up exchanges with purifiers, oxidisers and utility slots.
New loot - Elephant Tusks: Replaces mammoth tusks, provides half the bone weight, and yields 200 crushed bone.
Spider spawning re‑balanced: Minimum distance from cave entrances tripled, a 5‑minute cooldown after a group is killed, and only one group may occupy a cave at a time.
Carbonweave armor & backpack recipe re‑worked: Now uses electronics and gold‑wire instead of large amounts of organic resin.
Tier‑3 kitchen sink added: Includes a UI icon and filtered‑water output. Tier‑4 sink renamed to Marble Pumped Sink with effectiveness scaling by cleaning‑efficiency.
Lithium‑tool toggle: Press ‘R’ to enable/disable; UI prompt added.
Mount ownership release (Homestead builds): Owners can release mounts, allowing other players to claim them.
Animal‑husbandry UI icons: New icons clarify breeding, feeding and gestation status.
Prototype NPC in Eden: Trades Vestiges for Ren (prototype stage).
Workshop sickles pipeline: Miasmic, Obsidian, and Super‑Cooled Ice sickles are queued for future release.
Network component update: Crafting benches can now draw water directly from batteries (rain reservoirs).
Radiation system overhaul: Emitters now scale with stack size, radioactive items can no longer be placed in bags, and small emitters are added to uranium nodes to create hotspot zones.
Genetic system for mounts and tames: Wild genetics are auto‑generated, gestation periods variable (default 1500 s), fertility checks require proximity to the female, and gestating mounts automatically seek a bed.
Visual updates: New “Super Rare Black Moa” texture, additional colour variants for Moa and Buffalo, and new “Tundra caves” prefabs (TU_SML_001, TU_MED_001, MED_003).
New items & recipes: Oil Can (Tier‑5), adjusted Oil Barrel recipe, Biomass → Material recipes, Banana Toast, Soybean → Milk, Worm‑spawner preview mesh, Animal Nesting Bed assets, and a prototype item to pick up and deploy tamed creatures.

Bug Fixes

Inventory swap bug fixed - 1‑stack items (oxygen tanks, water‑skins, etc.) are now recognised as valid swap targets.
Creature floor‑angle calculation corrected - NPCs can walk up ramps (walkable angle increased from 45° to ~50°).
Mounts/tames drinking logic fixed - they now drink when food is below 75 % and no longer stand up abruptly when hungry or thirsty.
Foliage respawning issue resolved - new validation prevents “dirty” foliage from re‑spawning.
Flat solar panels now correctly count as solar panels for mission objectives after a base‑class change.
Building pieces no longer create dynamic materials each tick.
Network component water‑draw from batteries updated for crafting benches.
Radiation‑related compile errors cleared.
Over‑encumbered tames spawn bug fixed.
Temporary fix for creature‑genetics values dropping below zero.
Mount gestation speed now triples when resting on an animal bed.
Mount fertility logic updated - males must be close to females (previous 2000 units range removed).
Spider group spawning limited - no multiple groups in the same cave and a 5‑minute cooldown after a kill.
Flat solar panel counting bug for missions fixed.
Workshop calf feature lock bug resolved.
Radioactive items can no longer be placed in player bags.
Radiation emitters correctly scale with stack size.
Uranium generator output increased from 10 000 to 100 000; transmutation rate adjusted.
Uranium node lighting now reflects remaining resource, and emitters only generate radiation when the node is placed.
MapSearchArea now works with the Icarus compass.
Mission 6 security door camera alignment fixed.
Cave entrance actor rotation issues corrected across multiple biomes.
Radiation audio now respects low‑level thresholds.
