**Describe the bug** If Node B is a child of Node A in a file that does not have an `ID` property, then a link from Node B to Node A will not be displayed. **What browser were you using?** Firefox **Additional context** I believe that the cause is this chunk of code in `index.tsx`: ``` if (!fileNode) { return [] } ``` This suggests that the behavior might be intentional, although I'm not sure what the rationale is.
