Hi @tonianelope could you open another issue with a swagger spec reproducing the erorr as this doesn’t seem to be the exact same problem

[tonianelope]

Hi am having a similar issue where I have the following definition see below: (RenamedExampleProperty is refrencing the definition of Example as it is the same property only with a different name). But the PR doesn’t fix the issue for me.

    "Language": {
      "description": "xxx",
      "allOf": [
        {
          "$ref": "#/definitions/CommonLanguageProperty"
        },
        {
          "type": "object",
          "properties": {
            "RemanedExampleProperty": {
              "$ref": "#/definitions/CommonExampleProperty/properties/Example"
            },
          },
        }
      ]
    },```
