In the unforgiving, post-apocalyptic world of Once Human, a player's territory is more than just a plot of land—it is their sanctuary, their fortress, and their ultimate expression of survival. Every resource harvested, every structure erected, and every Deviant secured within an Isolated Securement Unit (ISU) contributes to the sprawling complexity of this personal domain. Yet, what happens when ambition meets limitation? The dreaded, soul-crushing 'Space Full, Unable To Place More' error message flashes across the screen, halting progress and shattering dreams of architectural grandeur. This is not merely a bug; it is the game's brutal reminder that space is the ultimate currency in 2026, and managing it requires cunning, strategy, and a deep understanding of the Memetics tree. But fear not, for this obstacle is not an end, but a challenge to be conquered!

The Inevitable Wall: Understanding the 'Space Full' Error

Why does this digital blockade appear just as you're about to place that perfect decorative fountain or a crucial new workstation? The answer is brutally simple: you have hit the absolute maximum capacity for your territory. Every single object, from a humble chair to a massive Isolated Securement Unit, consumes a predefined amount of this invisible spatial resource. The game, in its infinite wisdom (or perhaps sadism), imposes this limit to force players into strategic planning. Can you truly afford to haphazardly clutter your base with non-essentials when every square inch could mean the difference between thriving and merely surviving? The error is a call to action—a demand to optimize, expand, and evolve.

The Ultimate Solution: Territory Expansion via the Memetics Tree

When the walls of your digital world start closing in, there is one glorious, definitive answer: Expand your territory! This is the primary and most powerful method to banish the 'Space Full' error into oblivion. By upgrading your territory, you fundamentally increase your base's maximum capacity, creating new horizons for construction, decoration, and essential item placement. But how does one achieve this monumental feat? The path leads directly through the mystical and complex Memetics tree.

  1. Locate the Key: First, you must navigate to the Logistics section of your Memetics tree. This is the hub for all base-management and expansion technologies.

  2. Unlock the Power: Within Logistics, you will find the coveted Territory Expansion upgrade. Behold its cost, a testament to its value:

    • 3 Ciphers

    • 200 Energy Links

    This is the price of freedom from spatial constraints!

  3. Initiate the Upgrade: After unlocking the technology, approach the heart of your domain—your Territory Terminal. Interact with it and select the 'Upgrade Territory' option. Witness as your domain's boundaries stretch, granting you the precious, empty space you so desperately crave.

The Hidden Culprit: Isolated Securement Unit (ISU) Limits

Wait, you've expanded your territory, but the pesky error persists? Do not despair, for there is often a second, more insidious limit at play. Have you considered your Isolated Securement Units (ISUs)? These vital containers for your Deviants come with their own strict capacity. The initial limit is a mere five units. If you've filled all five, the game will stubbornly refuse to let you place anything else, throwing the same 'Space Full' error as if your entire territory was packed!

The solution, once again, lies within the boundless possibilities of the Memetics tree. Under that same Logistics category, you will find not one, but two separate expansions dedicated solely to increasing your ISU limit. Unlocking these is non-negotiable for any serious Deviant collector or strategist. By increasing your ISU capacity, you effectively clear a major hidden obstacle to your territorial expansion.

Pro-Tips for the Spatial Strategist

Beyond the major expansion paths, a master of territory management in 2026 employs several key tactics:

  • The Art of the Tidy Base: Before you expand, look inward. Are there redundant or purely decorative items hogging valuable space? Sometimes, the most effective way to create room is through ruthless optimization. Organize, stack, and streamline!

  • The Classic Reboot: When all else fails, or if the error seems buggy, never underestimate the power of the age-old IT solution. Try logging out of the game completely and logging back in. Similarly, ensure your game is updated to the latest version; developers are constantly tweaking and fixing spatial calculation bugs.

  • Plan Like a Pro: Use the initial space limitation as a design challenge. Sketch a layout! Prioritize essential crafting stations, storage, and defense before adding aesthetic flourishes. A well-planned base is a efficient base.

Conquering Your Domain

The journey in Once Human is one of constant growth against overwhelming odds. The 'Space Full, Unable To Place More' error is merely one of the first major gates you must pass through. By mastering the Memetics tree, strategically upgrading your territory and ISU limits, and maintaining a disciplined approach to base layout, you transform from a cramped survivor into a lord of your own expansive, thriving domain. Remember, in the world of 2026, space isn't just the final frontier—it's the first resource you must learn to conquer.
