Publish blocked: verse_validate_publish_error "Ambiguous identifier" in sys/published (live) code after 43.00. Candidate already fixed

Summary

Publishing a new version of my island fails Verse validation with an “Ambiguous identifier” error. The error cites the CURRENTLY LIVE code in sys/published, not my candidate. The new 43.00 compiler rejects a name clash in the live version. My candidate already fixes it on both sides (the local variable is renamed and the content folder is renamed), so I can’t clear the error from my project. This looks like the same issue as FORT-1160023 (live code made ambiguous by a newer compiler/API), which was fixed on Oct 19, 2026.

What Type of Bug are you experiencing?

Verse

Steps to Reproduce

  1. Live island’s published Verse has a local variable LevelTags in hv_game_manager.verse (FindDevices), plus a content folder HV_Kit/LevelTags, which is an implicit Verse module brought in by using { /imbravo@fortnite.com/HussValley/HV_Kit }.
  2. Under 43.00 that is now an ambiguous identifier (it compiled fine when it was published).
  3. In the candidate: rename the local to FoundLevelTagFx and rename the folder to HV_Kit/HvLevelTagFx. BuildAll in UEFN returns no errors.
  4. Upload a new private version and try to publish it in Creator Portal.

Expected Result

Validation compiles the candidate, or compiles the live version with the compiler it was published with, and the publish goes through.

Observed Result

Module caca706a-ce92-4fe4-9da2-a336b30ac9b7 in candidate link 0358-2966-9184?v=1 has error: “Ambiguous identifier; could be (/imbravo@fortnite.com/HussValley/hv_game_manager/FindDevices:)LevelTags or (/imbravo@fortnite.com/HussValley/HV_Kit:)LevelTags” in file: “C:/build/FortniteGame/Plugins/GameFeatures/caca706a-ce92-4fe4-9da2-a336b30ac9b7/sys/published/Content/hv_game_manager.verse” at line: 2652
verse_validate_publish_error

The same error and line number came back on every new candidate link, including ones made after the fix. The cited line doesn’t match the candidate’s current file.

Additional Notes

  • Only workaround reported on the forums (thread “Failing Verse Persistence after 38.0 for Ambiguous identifier…”) is reverting the active release to V1, which risks player persistent data. I’d rather not do that on a live island.
  • Request: allow this publish / skip the live-code recompile for this module, or apply the same fix as FORT-1160023.
  • Happy to provide logs (UEFN Help > Report a Bug).
