What Type of Bug are you experiencing?

Lore

Steps to Reproduce

  1. Open my project PansPracticeMap7.
  2. Click Check In.
  3. Lore creates an automatic backup commit on my personal branch, then the merge into main fails.

Expected Result

Check-in succeeds and main gets my current project state.

Observed Result

Check-in fails every time with:

rehashing commit: The system cannot find the file specified. (os error 2)
at lore-storage\src\error.rs:7 - open file: …\Content\KavookS\T_KS_Gi_Speed.uasset
at lore-revision\src\immutable.rs:417 - writing immutable content from file
at lore-revision\src\commit.rs:1951 - Failed writing file Content/KavookS/T_KS_Gi_Speed.uasset to immutable store
at lore-revision\src\branch\merge.rs:3864 - rehashing commit

Details:

  • Last successful check-in to main: revision 905, Sep 1 2026.
  • Since then 39 automatic backup commits (revisions 906-944) piled up on my personal branch and never merged into main.
  • About 3,890 files were deleted from disk after those backups. The merge still tries to read them from disk and aborts on the first missing one.
  • “lore repository verify state” reports “Multiple nodes have identical name” for 23 folders (e.g. Content/ExternalActors, Content/Meshes, Content/UIse, Content/PieceSection, Content/EditSystem, Content/Assets_1v1).
  • 3,048 of the deleted files are inside those duplicated folders. “lore stage ” fails for them with “Invalid path”, so I cannot register the deletions.
  • After the failed check-in, the project got stuck at “OpenProject_ConnectRevisionControl - Begin” on open. “lore status --reset” fixed the opening, but check-in still fails.
  • This looks like FORT-1155571 (thread “Lore checkout error”, marked fixed for 43.00 / 44.20). I am on 42.40 (CL 59343437), Lore client 0.8.6-nightly+338_3666.

I need check-in working to share the project with a team member. My local files are complete (I have a full backup). Could someone repair the duplicated folder nodes on the server side, or tell me a safe way to make my current local state the new main revision without losing the link to my published island?

Thanks!

Additional Notes

The project opens and publishes normally; only check-in is broken. I can provide full Lore.log and editor logs if needed. Please do not suggest Revert / Sync Latest, since that would overwrite my current local work.
