Uneditable Guides - Illustrator

[MtMcKinley]

Hey all, I'm working on an illustrator project and am using a lot of guides... most of my guides I can edit and move around just fine, but there is one guide - just one - that I cannot edit or delete at all. It is not on any locked layer, guides are not locked, nothing else I have seen has led me to any solutions, and I've tried most everything. Has anyone encountered this error before? I'm not sure if it's a bug or if I'm just not looking in the right places.

Have you tried Unlock All under the Object Menu?

The guide lock feature appears to occasionally get corrupted, acting as if locked for one, some, or all guides, but not indicated by either a layer lock or a document-level all-guide lock. This will cause frustrating attempts to select guides, which may appear to be selected for a split second just before being immediately deselected. When this occurs, as it recently often does, toggle the document-level all-guide lock on and back off again; use menu View > Guides > Lock Guides, then View > Guides > Unlock Guides, or double-tap the shortcut shown (Ctrl+Alt+; on Windows or Cmd+Opt+; on a Mac).
