Summary
Summary Since the 43.00 update (Nov 1), Project > Launch Memory Calculation fails every time on my published island. The failing request is the MemoryManifest.json for the root module of the Epic “Low Poly Dungeons” referenced content, not for my own content. Signing out/in, restarting UEFN and retrying after the announced fix did not help (still failing at 23:56 UTC Nov 1).
Steps to reproduce
Open the project (it uses Low Poly Dungeons as referenced content).
Project > Launch Memory Calculation.
It fails after a few seconds (or after the module finishes cooking).
Expected: memory calculation completes (last good result Oct 25: 79,062). Actual: fails with ContentServiceFailure / module_not_found.
Error from UnrealEditorFortnite.log LogValkyrieMemoryCalculation: Warning: Memory calculation failed: Valkyrie::MemoryCalculation::Errors::ContentServiceFailure: [Content service request failed: Could not find the requested resource, (errors.com.epicgames.content-service.module_not_found: “host”: “content-service.bfda.live.use1a.on.epicgames.com”, “method”: “GET”, “path”: “/api/content/v4/artifact/e777747b-f386-4960-af25-0774fb922553%3Apc-sm6/job/c85b3f9d-3885-4ab5-a493-1ecaddb77a32/cooked-files/owner/debug/MemoryManifest.json”

Details
Failing module: 85630e2c-4be9-b095-5dbf-77bf87ddd0d8 (artifact e777747b-f386-4960-af25-0774fb922553, pc-sm6, cook job c85b3f9d-3885-4ab5-a493-1ecaddb77a32)
That module is the root of referenced content “LowPolyDungeons” (/projects.epicgames.com/_8dd8804d4cff25204669f596d309dd0b). It loads fine in the editor.
The same artifact and job id fail on every attempt, so the manifest for that cook seems missing on the server.
Other MemoryManifest requests in the same runs return HTTP 500 “unknown exception”.
The Content Browser also logs “Cannot add alias /projects.epicgames.com/8dd8804d4cff25204669f596d309dd0b/Mesh_Dungeons…” so the pack folder doesn’t show.
A different project of mine with no referenced content runs Memory Calculation fine on 43.00.
My own module (152b5c0e-4ea0-f7dc-b9ae-a3aac275e0e2) cooks fine.
UEFN: 6.0.0-59596594+++Fortnite+Release-43.00, Windows.
Can the Low Poly Dungeons pack be recooked / its memory manifest regenerated for 43.00? Happy to send full logs.
