Verse Build Error on Republishing Fall Guys Island After Environment Changes

Summary

We successfully published our Fall Guys island titled “Only Up Remastered” without any issues. After making minor changes to the environment (with no changes to the Verse code), we attempted to republish the island. During this process, we encountered two Verse build errors related to the MakeCountdownTimer function and its dependencies, even though the code compiles successfully. The issue only appears when trying to launch the session for the publishing process.

We rolled back to the last working project using Unreal Revision Control, but even with the same exact project that is currently live, the error persists.

Here is the error message we received:
E:/UEFN/Fall_Guys_OnlyUP/Plugins/Fall_Guys_OnlyUP/sys/published/Content/CustomCounter.verse(10,1, 13,1): Script error 3593: Definition (/gamersroof@fortnite.com/Fall_Guys_OnlyUP:)MakeCountdownTimer is accessible universally, but depends on (/gamersroof@fortnite.com/Fall_Guys_OnlyUP:)countdown_timer, which is only accessible from subpaths of /gamersroof@fortnite.com/Fall_Guys_OnlyUP. The definition should be no more accessible than its dependencies.

What Type of Bug are you experiencing?

Publishing

Steps to Reproduce

1] Publish the island without issues.
2] Make minor changes to the environment (no Verse code changes).
3] Attempt to Launch the Game.
4] Encounter Verse build errors during the session launch for publishing.
5] Roll back to the last working version using Unreal Revision Control and attempt to launch again.
6] Same Verse build errors occur even with the rollback.

Expected Result

The island should republish successfully without Verse build errors, as the Verse code was not modified and the project previously compiled and published without any issues.

Observed Result

The republishing process fails due to Verse build errors related to the accessibility of MakeCountdownTimer and its dependency countdown_timer, despite the code compiling successfully. The issue persists even after rolling back to a previously working version.

Platform(s)

Additional Notes

The code compiles successfully, but the issue only appears during the session launch for the publishing process. Rolling back to the last working version through Unreal Revision Control did not resolve the issue.
