Summary
Revision Control (Lore) fails to connect on all UEFN projects, including brand-new ones, after a crash occurred on one project. Client logs show the root cause is a corrupted data fragment that fails server-side decompression, surfaced to the user as a misleading “NotFound” error.

What Type of Bug are you experiencing?
Unreal Revision Control
Steps to Reproduce
- Have an active UEFN project connected to Revision Control (Lore)
- Experience a crash during a revision control operation (e.g. check-in/sync)
- Relaunch UEFN and attempt to reconnect to Revision Control on the same project
- Attempt to connect to Revision Control on a brand-new project as well
Expected Result
Revision Control should reconnect successfully, or at minimum recover/report a clear, actionable error. New projects unrelated to the crash should be unaffected.
Observed Result
Connection fails on the originally affected project AND on every new project created afterward, with:
Failed to deserialize revision states: Not found | NotFound(Traced { inner: NotFound, trace: Trace { locations: [Location { file: “lore-revision\src\state.rs”, line: 546, column: 37 }] } })
Lore.log shows the actual failure one step earlier:
[lore_storage::compress] Oodle decompress failed: 0
[lore_storage::read] Fragment fb62bd84e15c4d108528d07e9d69454664883290b4acd1a433e0785f337b9627 failed decompression/verification
Occurs when querying staged/pending status (staged:1, sync_point:1).

Fully local reset performed with no effect (deleted project .lore folder, wiped UnrealEditorFortnite, reinstalled UEFN, cleared Launcher webcache, renamed global lore/urc cache folders — fresh empty local client hits the identical error instantly). This confirms the corrupted fragment is stored server-side, tied to my account, likely a leftover staged change from the original crash.
