ICARUS RAD_O2 Creature Placement: Week 250 Fix
Quick Answer
If ICARUS RAD_O2 appears unable to place a required creature or move the quest forward, first confirm that the client and host run Week 250 build 3.0.28.157342 or later. RocketWerkz documented one precise cause: two RAD_O2 quest markers were using the same tag, which caused problems with creature placement. Week 250 records a fix for that tag conflict. On the corrected build, verify the exact RAD_O2 objective, keep the mission state intact, and observe whether the expected creature appears through the normal quest flow. The release note does not identify the creature, reveal either marker coordinate, publish a manual spawn command, or promise that every prospect already stuck on an older build will repair itself. It also does not say that relogging, leaving the area, killing another creature, moving structures, or editing a save resets this state. Treat the shared marker tag and Week 250 boundary as verified; keep every other cause and recovery method separate unless current evidence supports it.

Before you set out
Prerequisites#
- Use Week 250 build 3.0.28.157342 or later on both the player client and the session host.
- Confirm the active task is RAD_O2 and record the exact objective text before changing the mission state.
- Preserve the current prospect while diagnosing; the official source does not authorize abandoning, deleting, or editing it.
- Keep the creature identity, marker positions, spawn trigger, and older-prospect recovery Unknown unless the live objective or another reliable source verifies them.
Why RAD_O2 creature placement could fail#
The Week 250 changelog describes an internal quest-marker conflict, not a general creature AI failure. Two RAD_O2 quest markers used the same tag. A quest system uses tags to distinguish or retrieve its intended locations and objects; when both markers shared one identifier, the release says the conflict caused issues with creature placement. That is the entire verified causal chain. The note does not name the creature, describe whether placement means an initial spawn, relocation, respawn, or objective handoff, and does not expose the marker coordinates to players. Those omissions matter. A missing animal, a creature outside the objective area, an unresponsive enemy, or a tracker that has not advanced may look similar, but the patch line does not prove they all share this cause. Use the exact RAD_O2 objective and build boundary to narrow the diagnosis. On Week 250 or later, observe the normal mission sequence once before changing anything. If the objective remains stuck, preserve the objective wording, map state, client and host builds, prospect age, visible markers, and any creature already present. Do not repeatedly leave and return, destroy nearby objects, or kill unrelated creatures simply to force a result. The official source records a software correction, not a player-operated reset. It also does not guarantee that updating rewrites every serialized quest marker in a prospect created before the patch. A remaining failure is therefore useful only when reported with its exact state rather than translated into a guessed workaround.
Route 02
Check an ICARUS RAD_O2 creature placement failure#
Use this order to test the documented Week 250 boundary without turning an internal marker fix into an unsupported spawn recipe.
Confirm the mission code#
Read the current mission or operation name and verify that it is RAD_O2. A different radiation task, Open World encounter, or ordinary creature spawn is outside this exact patch line.
Record the active objective#
Capture the tracker text before moving, attacking, or interacting. The source does not say which RAD_O2 step used the duplicate markers, so the visible objective is essential context.
Check the client build#
Confirm Week 250 build 3.0.28.157342 or later. An older client is below the verified release boundary and cannot establish that this fix is present.
Check the host build#
Verify the host or dedicated server uses the same corrected build. Mission placement logic may be controlled by the session, so a current client alone is insufficient evidence.
Note when the prospect began#
Record whether the mission state was first created before or after Week 250. The patch fixes the conflict but does not promise migration of every older serialized marker.
Observe visible mission markers#
Use only the markers presented by the current game. The official source gives no coordinates and no instruction to travel to a guessed alternate point.
Let the normal step run once#
Follow the live objective without repeatedly crossing boundaries or changing unrelated world objects. One preserved attempt is more informative than several undocumented trigger guesses.
Check for the expected placement result#
Observe whether a quest creature appears or the tracker advances. Do not assign a creature name that the Week 250 note never supplies.
Preserve a remaining failure#
Save the objective, build numbers, host type, prospect age, marker behavior, creature presence, and actions taken in order. Keep interpretation separate from observation.
Avoid destructive resets#
Do not delete the prospect, edit saves, use console spawning, or promise that relogging repairs the markers. None of those actions is documented in the cited release.

Fault ledger
If RAD_O2 still will not place the creature#
- The host is older than Week 250
- Update and restart the host before judging this fix. A current client cannot prove that the session runs corrected quest logic.
- The task is not RAD_O2
- Stop applying this diagnosis. The duplicate-marker statement is scoped to RAD_O2 and does not establish behavior in another mission.
- The tracker is on an unidentified step
- Preserve its exact text and visible markers. The release does not tell us which objective used the conflicting tags.
- The prospect began before Week 250
- Record that boundary. The source does not guarantee that an older saved mission reconstructs its marker state after updating.
- A workaround proposes spawning or editing
- Require separate authoritative evidence. Week 250 documents a code fix, not a console command or save-edit procedure.
Field questions
RAD_O2 creature placement questions#
- What caused the documented RAD_O2 failure?
- Two quest markers used the same tag, causing problems with creature placement.
- Which release contains the fix?
- Week 250 build 3.0.28.157342-rel-DangerousHorizons is the verified boundary.
- Which creature was affected?
- The saved official note does not name it, so the creature identity remains Unknown here.
- Where are the two quest markers?
- No coordinates or player-facing marker names are published in the cited source.
- Will updating rescue an older stuck prospect?
- That guarantee is not documented. Preserve when the prospect began and its exact current objective.
