Icarus Update 2.3.28.147909 Brings Storage Crafting Fixes and Spider Adjustments
The latest Icarus update refines craft bench storage interactions, updates cave spider spawn distances, and addresses unexpected foliage respawns.
The latest Icarus patch implements targeted fixes for crafting storage, creature behaviors, and cave navigation. Developers focused this week's update on resolving persistent quality-of-life snags while preparing backend systems for upcoming content expansions.
Crafting Storage and Inventory Improvements
Deployable storage objects like batteries, rain reservoirs, and portable tanks now connect directly when determining required resources at crafting benches. For example, recipes such as Pickled Carrots at the kitchen bench now pull water from connected storage even without an active water pump. In addition, survival slots for oxygen tanks and waterskins now permit direct drag-and-swap interactions.
Creature and Spider Spawn Tweaks
Spiders now feature stricter spawn rules near cave entrances. The minimum player distance required to trigger a spider spawn has tripled, and groups can no longer spawn at a cave if any spiders are already present or if a group was cleared within the last five minutes. Furthermore, a fix ensures mounts and tames drink properly when their food drops below threshold levels, preventing them from abruptly standing up from rest.
Resource and Recipe Adjustments
Carbonweave Armor and Backpack recipes now require electronics and gold wire instead of large quantities of organic resin. Elephant drops have also been updated, replacing mammoth tusks with new elephant tusks that weigh half as much and yield 200 crushed bone.
Foliage Respawn Root Cause Fixed
Developers identified and resolved an issue where foliage was unintentionally respawning inside player bases. Changes made to the foliage setup Datatable during preparation for a new map caused a mismatch with existing prospects, triggering a full refresh. A new process is now in place to prevent similar data mismatches from dirtying existing environments.
Why this patch matters
Update 2.3.28.147909 clears out frustrating inventory and base-building bugs while tightening up enemy spawn logic, making day-to-day survival tasks run smoother.
