What Type of Bug are you experiencing?
Creator Portal
Steps to Reproduce
- Create a UEFN island using Fortnite Sidekick NPCs.
- Build Verse and validate the project successfully.
- Run memory calculation and create a private version after the July 23 publishing unlock.
- Wait for all UEFN Publishing Report checks to turn green.
- Open the private version in Creator Portal.
- Observe that Creator Portal marks the version as failed and prevents release creation.
Expected Result
The private version should pass Creator Portal validation and allow creation of a release because Sidekick NPC publishing opened on July 23.
Observed Result
Creator Portal marks the private version as failed. UEFN reports no validation errors and logs that the content was successfully activated on all platforms.
