Quick answer
You are probably not permanently stuck after Hotfix 2, because Unknown Worlds says more Troilite resource areas were added in the late-game region. Still, stop spending Troilite, check Mineralized Clinker route notes, and save the next sample until you know whether Metal Farm or Mangalloy needs it first.
Field notes before calling it a softlock
Stop spending first
The worst move is to find one new sample and immediately spend it on the wrong branch. Freeze Troilite spending until the blocked recipe is written down.
Separate bug fear from route uncertainty
Hotfix 2 added more late-game Troilite areas, so a missing sample is more likely a route problem than a permanent save problem. Check the route calmly.
Make the next find traceable
When you find a sample, mark the route, note the nearby terrain, and keep the sample in a named locker. Future-you will not remember the canyon by vibes.
What to do before you panic
Stop crafting with Troilite
Do not turn every sample into Mangalloy or other late recipes just because the fabricator allows it. Treat the next piece like a recovery item until your Metal Farm route is clear.
Check the Hotfix 2 route
Unknown Worlds says Hotfix 2 added more Troilite resource areas in the late-game region. That means old launch-week advice about a single tight source may be out of date.
Look for Mineralized Clinker wording
Some route notes talk about Mineralized Clinker rather than shouting Troilite in the title. If you only search one word, you may miss the deposit clue you need.
Plan Metal Farm before spending again
PC Gamer route reporting ties Metal Farm progress to late rare-metal planning. If you are trying to recover, write down the next craft first, then spend only what that craft truly needs.

Recovery checklist
| Problem | Best next move |
|---|---|
| I spent my first Troilite | Stop crafting, recheck Hotfix 2 Troilite routes, and keep the next sample unspent. |
| I cannot find the deposit name | Search route notes for Mineralized Clinker as well as Troilite. |
| Old guides say there is only one source | Treat that as launch-week advice until it has been retested after Hotfix 2. |
| I need Metal Farm progress | Check the Metal Farm chain before using rare metals on optional crafts. |
| I am early game | Do not force a deep recovery run yet. Fix oxygen, tools, storage, and safer resource loops first. |
Do not promise a magic fix
This page is a recovery checklist, not a coordinate dump. Early Access resource placement can change, and the official note confirms more areas rather than publishing a full map.
FAQ
Can I softlock myself by using Troilite in Subnautica 2?
Hotfix 2 makes a permanent softlock less likely because more Troilite resource areas were added, but careless spending can still slow your route badly.
What should I do with my next Troilite?
Hold it until you know your next required craft. If Metal Farm progress is your goal, check that chain before making optional Mangalloy crafts.
Is Mineralized Clinker the same issue?
Yes for search intent. Players looking for Mineralized Clinker are usually trying to solve the Troilite route or recover from spending a rare sample.
Should I restart my save?
Do not restart just because the first sample was spent. Recheck Hotfix 2 routes first and keep the next sample aside.
