ICARUS Polymeriser Oil Crafting XP: Week 251 Fix
Quick Answer
ICARUS Week 251 fixes a resource-crafting experience bug that specifically affected cases such as the Polymeriser crafting items with oil. Before this build, the craft could complete while providing no crafting experience. Confirm that both client and host run Week 251 build 3.0.29.157838 or later, record your experience before one normal oil-based craft, let the craft finish, and compare the displayed total afterward. The official release confirms the missing-XP fix but does not publish how much XP any recipe awards, whether queued or offline crafts behave differently, or whether experience lost before the patch is granted retroactively. Do not turn Unknown XP values into zero, assume every Polymeriser recipe uses oil, or promise reimbursement for earlier crafts.

Before you set out
Prerequisites#
- Use Week 251 build 3.0.29.157838 or later on the client and session host.
- Confirm the item is being crafted in the Polymeriser and that the live recipe consumes oil or another displayed resource.
- Record the visible experience total before testing one ordinary craft.
- Do not assume a recipe-specific XP amount, multiplier, queue rule, or retroactive award; the official note publishes none.
Why ICARUS Polymeriser oil crafting could give no XP#
The Week 251 improvement list describes a broader resource-crafting issue: crafting with resources was not providing experience in affected cases. It then names the Polymeriser as the concrete example, saying it could provide no crafting experience when producing items with oil. This establishes the affected activity and the missing result, but not the internal formula. It does not say every Polymeriser recipe was affected, that oil has a special XP multiplier, or that a successful craft should award a fixed number across all recipes and character states. The safest verification is therefore comparative. Confirm the correct build, note the visible experience value, complete one normal resource craft in the named station, and observe the change. A value that changes supports current operation; a value that does not change on the fixed build is a new observation that needs its recipe, host, and build preserved. Do not infer a numeric expected award from the word “experience,” and do not treat past missing experience as recoverable unless a separate source documents retroactive credit. Keep the crafted output, consumed resource, and experience observation in the same record. A completed item proves the recipe resolved, while the before-and-after display answers the separate XP question. If several items were already queued, do not divide one total change into guessed per-item awards; repeat later with one item only if another legitimate verification is needed. Also keep character experience separate from station progress, talent effects, or other interface counters. The official wording concerns crafting experience, but it does not define every screen label or bonus that a later build may display. This narrow comparison protects useful evidence without turning a successful test into an unsupported formula.
Route 02
Verify Polymeriser crafting experience safely#
Use one bounded craft to test the fixed behavior without wasting a queue of materials or inventing the expected amount.
Confirm Week 251 on both sides#
Check client and host versions. A server still on an older weekly build can invalidate a client-only test.
Open the Polymeriser#
Verify the station name in the current interface. Keep other benches and automated devices outside this specific test.
Choose a live oil-based recipe#
Select a recipe whose current card visibly uses oil. The release gives no permanent recipe list, so rely on the live card rather than memory.
Record the starting experience#
Capture or write down the character’s displayed experience immediately before starting the test. Avoid estimating from the progress-bar shape alone.
Craft one item normally#
Run one complete craft with the required resources. A single item limits material loss and keeps the observation attributable.
Let completion register#
Wait until the station reports the item complete and the game has had a normal opportunity to update the experience display.
Compare the visible total#
Record whether experience increased. The supported expectation after Week 251 is that affected resource crafts no longer silently provide none.
Do not assign an expected number#
The source does not publish XP per recipe, difficulty scaling, talents, bonuses, or rounding behavior. Report the observed change without promoting it to a universal value.
Preserve a remaining mismatch#
If no change appears, save the build, host type, recipe name, resource card, before-and-after values, queue state, and whether the prospect began before the update.

Verified Polymeriser XP boundaries#
- Affected category — crafting with resources could fail to provide experience.
- Named example — Polymeriser items crafted with oil.
- Observed defect — the craft could provide no crafting experience.
- Fix boundary — Week 251 build 3.0.29.157838.
- Not published — XP amounts, recipe list, multipliers, queue behavior, offline behavior, talents, rounding, or retroactive credit.
- Search volume, keyword difficulty, and external SEO score remain Unknown.
- Preserve the tested recipe, build, host, and exact before-and-after experience display together.
Fault ledger
If Polymeriser XP still appears missing#
- The host is not on Week 251
- Update and restart the host before testing. The official fix boundary cannot be verified from an updated client alone.
- The recipe does not visibly use oil
- Do not apply the named oil example to a different unverified recipe. Record that recipe separately with its live inputs.
- The progress bar looks unchanged
- Compare exact displayed totals if available. The release does not establish that every award is visually large enough to judge from bar shape.
- Old missing XP was not restored
- The patch confirms future crafting behavior but does not promise retroactive experience or reimbursement.
- A chart gives an exact XP amount
- Require current authoritative evidence tied to the recipe and build. Week 251 does not publish recipe-level values.
Field questions
Polymeriser crafting XP questions#
- Was the no-XP result a documented bug?
- Yes. Week 251 names Polymeriser oil crafting as an affected resource-crafting case.
- Which build fixes it?
- The verified boundary is Week 251 build 3.0.29.157838-rel-DangerousHorizons.
- How much XP should one oil craft give?
- Unknown from the official release. Use the current observed values and do not guess a universal amount.
- Will the game repay XP lost before the patch?
- Retroactive credit is not documented in the cited source.
- Does the fix prove every station and recipe works?
- No. The release describes affected resource crafting and names the Polymeriser oil case; other cases need their own evidence.
