RAD_O1 Stew completion · Week 250–251 current-player evidence boundary
ICARUS RAD_O1 Antiradiation Stew Quest Not Completing
Quick Answer
If the ICARUS RAD_O1 Antiradiation Stew quest step does not complete, confirm that the client and host run Week 251 build 3.0.29.157838 or later. Before that update, the quest checked for the stew buff; Week 251 adds a fallback that checks whether the item was consumed, allowing what the publisher calls “full players” to complete the step. Consume the exact quest item through the normal interface, keep the tracker visible, and wait for the objective to register before changing inventory or repeating the action. This version check distinguishes current quest logic from an older host still running the original buff-only test. The official wording does not explain whether “full” means food, buffs, health, inventory, or another state, so this guide does not choose one. It also does not publish the stew recipe, buff duration, radiation values, exact mission sequence, or a guaranteed recovery for a step already stuck on an older build.

Before you set out
Prerequisites#
- Use Week 251 build 3.0.29.157838 or later on both the player client and session host.
- Confirm the active mission or operation is RAD_O1 and the tracker specifically requests Antiradiation Stew consumption.
- Use the exact item named by the live objective and record its name before consuming it.
- Keep the publisher phrase “full players” unresolved; do not convert it into an inventory, food, health, or buff-cap fact without another source.
Why the RAD_O1 Stew step could fail to complete#
The Week 251 changelog identifies the quest’s completion check. RAD_O1 was looking for the buff from Antiradiation Stew. That single check could miss a valid consumption, so the update adds a fallback that checks the consumed item itself. The publisher says this allows “full players” to complete the quest, but does not define the state. It would be inaccurate to rewrite that phrase as a full inventory, full stomach, complete food-buff bar, maximum health, or maximum radiation resistance. The verified claim is narrower: valid item consumption can now satisfy the step even when the expected buff check alone does not. This distinction shapes the safe test. Confirm the fixed build and exact mission step, consume the named item normally, and observe the tracker. Do not intentionally clear food, discard unrelated items, take radiation damage, or change health merely to fit an unsupported theory. The item event and buff state are two possible signals in the corrected logic, not instructions for manipulating character state. If the step remains incomplete, preserve what was consumed, the tracker wording, the before-and-after item count, the current build on both sides, and whether the prospect began before Week 251. The release does not state that repeating the item stacks progress or that an already-stuck objective will always rescan prior consumption. One controlled attempt on the fixed build is more informative than consuming several items without recording the result.
Route 02
Fix an ICARUS RAD_O1 Antiradiation Stew quest not completing#
Verify the corrected item-consumption path without guessing what “full players” means or wasting multiple quest items.
Confirm RAD_O1#
Read the active mission name and objective. Do not apply this fix to another radiation mission, a generic survival buff, or ordinary food use.
Check both running builds#
Verify Week 251 build 3.0.29.157838 or later on client and host. A mismatched server can retain the older check.
Record the objective text#
Capture the tracker wording before consuming anything. That separates the Antiradiation Stew step from later RAD_O1 tasks.
Identify the exact item#
Confirm the inventory item is Antiradiation Stew. The source does not say another radiation consumable satisfies the same quest check.
Record the starting item count#
Note the count so that consumption can be distinguished from moving, dropping, equipping, or failing to use the item.
Consume one item normally#
Use the standard live interaction once. Week 251 adds a consumed-item fallback, so the event itself is the verified signal.
Watch the tracker register#
Give the objective a normal opportunity to update before opening other menus, reconnecting, or consuming a second item.
Do not manipulate an assumed full state#
The changelog does not define “full players.” Avoid changing food, health, inventory, or buffs just to validate a guess.
Preserve a remaining failure#
Record build, host type, prospect age, objective text, exact item, count change, tracker result, and any visible buff without interpreting the ambiguous cause.
Avoid unsupported recovery#
Do not promise a restart, save edit, mission abandonment, or repeated consumption as an official reset. None appears in the source.
Pocket list 03
Verified RAD_O1 Stew boundaries#
- Affected mission — RAD_O1.
- Quest item — Antiradiation Stew.
- Old check — the quest relied on the associated buff.
- Week 251 change — a fallback also checks the consumed item.
- Publisher result — this allows “full players” to complete the quest.
- Unknown — what “full” means, recipe, duration, radiation values, exact later steps, repeated-item behavior, and old-prospect recovery.
- Search volume, keyword difficulty, and external SEO score remain Unknown.
Fault ledger
If RAD_O1 still does not acknowledge the Stew#
- The host is older than Week 251
- Update and restart the host before testing. The fallback belongs to the Week 251 quest logic.
- The item count did not decrease
- Verify the item was actually consumed through the live interaction; moving or selecting it is not the documented event.
- A different radiation item was used
- Return to the exact objective and item name. The source verifies Antiradiation Stew, not every consumable with a related effect.
- The step was already stuck before updating
- Preserve that boundary. The note adds a current check but does not guarantee replay of an older consumption event.
- A guide says to empty inventory or food slots
- Treat that as unverified unless it has a separate current source; Week 251 never defines the publisher’s “full” state.
Field questions
RAD_O1 Antiradiation Stew questions#
- What did Week 251 change?
- RAD_O1 now has a fallback that checks the consumed Stew item rather than relying only on its buff.
- What does “full players” mean?
- The saved publisher source does not define it. This guide intentionally leaves inventory, food, health, and buff interpretations Unknown.
- Which build contains the fallback?
- Week 251 build 3.0.29.157838-rel-DangerousHorizons is the verified boundary.
- Can another radiation consumable complete the step?
- That is not established. The official line specifically names Antiradiation Stew.
- Will an old stuck step recover automatically?
- The source does not guarantee replay or repair for a prospect already stuck before the patch.
