ICARUS Hotfix 3.0.21.155383 Fixes Mission Progression Bugs
The update addresses broken spawns, duplicated wolf dens, structure cleanup, and objectives that failed to appear across several missions.

ICARUS Hotfix Version 3.0.21.155383-rel-DangerousHorizons addresses mission bugs that could block progression, prevent creatures and soldiers from appearing, or leave structures and objectives in the wrong state. RocketWerkz detailed the changes in the official Steam announcement.
The fixes apply to both new missions and prospects already in progress after the game is updated. Livewire receives several corrections, including one that allows existing prospects to continue if players killed the wolf pack before activating the travel event.
Other missions receive spawn and objective fixes. Nexus and Relics correct missing creature and soldier spawns, while Courier addresses soldier appearances at camps. Breakout also fixes structure spawning and decal cleanup, and Liberation corrects its Secure Status mission step.
