Subnautica 2 'Cannot Deconstruct: Has Attachments' — Fix
'Cannot deconstruct: has attachments' in Subnautica 2 with nothing left attached? A known base-building bug from moved wall devices — step-by-step fixes inside.
Last updated: 2026-06-22
What the message means
When you point the builder at a corridor, room or foundation to Deconstruct it and get "Cannot deconstruct: has attachments," the game thinks something is still attached to that piece — you have to remove everything on it before the piece itself will come down. Normally, clearing the visible hatches, windows, lockers and so on lets you continue.
⚠️ But many players see the warning even after everything is emptied and nothing is left — that's a known Early Access bug, not something you did wrong.
Why it gets stuck (ghost-linked objects)
The cause is the new modular base's internal room-linking system. Certain devices — especially ones that have been moved — stay "ghost-linked" to their original wall or room. Common culprits:
- Lockers and fabricators (after being moved off a wall)
- The Battery Charger — also the usual source of "battery charger disabled" type problems
- Reinforcements and solar panels and other wall-mounted / exterior devices
The tell-tale sign: once a wall-mounted item is moved off its wall, that wall or room still believes something is attached, so it can't be deconstructed, shrunk or remodelled — and the real attachment isn't always in the room you're trying to remove; it can be elsewhere in the base.
How to fix it (try in order)
- Strip every attachment, inside and out: empty and remove the lockers, terminals, fabricators, Battery Charger, reinforcements and solar panels on the piece — including exterior pieces. Don't forget wall-mounted devices you moved elsewhere in the base.
- Save and reload: a fresh reload sometimes clears the phantom attachment data — then retry the same piece.
- Shrink from a different contact point: if you're recycling the whole thing, shrink from different angles, or break one big run into several smaller sections — this often gets around it.
- Last resort — "Refund Base": the pause menu has a Refund Base option; pick the base you want gone and it's refunded wholesale, leaving a beacon with the Titanium ingredients in its place. This is the community's most reliable fix.
⚠️ Refund Base caveat: moved lockers and fabricators can be deleted along with their contents (the game still counts them as attached to the original room). So empty those containers first before refunding, or expect to lose what's inside.
Mistakes to avoid
- Don't remove random nearby pieces — it makes the save harder to diagnose and can create a new power or storage problem. Work on one target and one attachment chain at a time.
- Don't delete save files or dismantle half your base before isolating the object that's blocking the deconstruction.
FAQ
Q: I emptied everything — why does it still say "has attachments"?
A: It's a known bug — a moved wall-mounted device (locker, fabricator, Battery Charger) left a ghost link, possibly elsewhere in the base. Check every attachment inside and out, then save and reload.
Q: My Battery Charger is disabled / won't deconstruct after I moved it.
A: Same bug. Fully remove it and reload the save; if it's still stuck, use Refund Base to recycle the whole structure.
Q: What's the most reliable fix?
A: Refund Base from the pause menu — but empty any moved lockers/fabricators first, or their contents go with them.
Q: Will it be patched?
A: Yes. It's an Early Access bug and the developers keep shipping hotfixes (e.g. the May 22 Hotfix 2). Filing a reproducible bug report helps.
Q: What should I do before deconstructing?
A: Empty and remove all attachments on the piece first — see the Base Building guide; for the Battery Charger and other power gear, see the Base Power guide.
