Summary

can someone please have an answer this is a gpt summary - I am having an issue with UEFN Revision Control/Lore. When I try to sync my projects, I receive the error “Sync failed — branch is archived.”

This is happening with multiple separate UEFN projects, not just one project.

Here is what happened:

My laptop unexpectedly shut down while I was launching UEFN.
I later discovered that there was a duplicate copy of one of my UEFN projects in OneDrive. I permanently deleted the OneDrive duplicate.
The original project is still in my Downloads folder and has not been deleted.
I have a collaborator with write access who was working on Verse in one of my projects.
I have not intentionally archived any branches or created new branches.
Multiple projects are now showing “Sync failed — branch is archived.”

I am concerned about losing my projects or Revision Control history.

Could you please check the server-side Revision Control/Lore state for my projects and determine:

Why the branches are showing as archived.
When/how they were archived.
Whether the branches and their revision history are still intact.
Whether the branches can be restored/unarchived safely.
Whether there is anything I should do with my local project copies while waiting.

I have kept the original local project copies untouched because I do not want to risk losing any data or revisions.

I can provide screenshots, project names/IDs, island codes, or any other information needed.

Additional Notes

urgent

Additional information: I noticed that the affected project has a nested folder structure that I don’t see in my other projects:

MammothMap\MammothMap\Lore

The first MammothMap is the project folder, and inside it there is another MammothMap folder containing a Lore folder.

I have not deleted, moved, renamed, or modified the Lore folder. I wanted to mention this in case it is relevant to the “Sync failed — branch is archived” issue. and there is anohter one because i tried to sync again

I have also noticed the same “Sync failed — branch is archived” error on multiple UEFN projects.

My original local project copies are still intact in Downloads.
