Summary
I can’t publish my UEFN island. The Creator Portal publish dialog blocks me for two reasons, even though UEFN reports both as fine: (1) Memory Usage shows “Action Needed - please run a memory calculation in UEFN while connected to a session”, although the memory calculation succeeds in UEFN while connected to a session and the portal never receives the result. (2) Experimental Features shows “Cannot publish while these experimental features are enabled: Experimental editor setting(s)”, although I have no experimental features enabled.

What Type of Bug are you experiencing?
Publishing
Steps to Reproduce
- Open the UEFN project (v43.00) and build Verse. The build succeeds.
- Launch a session and wait until it is connected and the game is running.
- Run the memory calculation (Memory Calculation window > Calculate).
- Upload a private version (Project > Upload to Private Version).
- Open the Creator Portal and click “Create Release” for that private version.
Expected Result
The private version is marked as memory checked, no experimental features are flagged, and “Continue” is enabled.
Observed Result
- Memory Usage: “Action Needed”. The editor log shows the calculation succeeded and was published to the session:
LogValkyrieMemoryCalculation: Display: Memory calculation complete: peak=27556112 threshold=314572800 sampled=1 success=true
LogValkyrie: [FValkyrieFortniteEditorSpatialMetrics::PublishMemorySession] Published memory calculation result to session 0
No upload of the result to the content service appears in the log, and there is no error or warning. - Experimental Features: flagged as “Experimental editor setting(s)”. However, every option under Project Settings > Experimental Access is unchecked, and the only extra system I use is the Scene Graph System, which is under “Beta Access”, not Experimental. The local validator passes (ValkyrieValidator_ExperimentalSettings : validated 6, invalid 0, errors 0, warnings 0), and the UEFN Publish Validation report says “Experimental Features: No issues found”.
- Every other check passes: Release type, download size (56.40 / 400 MiB), asset status, Verse compatibility, in-island transactions.
- The “Continue” button stays disabled.
- It happened on two private versions (0995-0005-0537 and 7098-2387-5204) on Nov 5 and again on Nov 6, 2026, after restarting UEFN.

Additional Notes
This looks like the v43.00 memory-report issue that was marked as resolved (thread 2848304), but it still happens for me. The experimental flag also looks like the known false positive (FORT-987117). I can provide the full UnrealEditorFortnite.log if needed.
