Default index pattern goes missing

Sure, I can do that. I only want to mention that it can take some (a lot of?) time until the problem reoccurs.

Currently I can see "config" dokument on .kibana index, can you please confirm that this is what we're looking for?

  "config" : {
    "properties" : {
      "buildNum" : {
        "type" : "keyword"
      },
      "defaultIndex" : {
        "type" : "text",
        "fields" : {
          "keyword" : {
            "type" : "keyword",
            "ignore_above" : 256
          }
        }
      },
      "discover:aggs:terms:size" : {
        "type" : "long"
      },
      "state:storeInSessionStorage" : {
        "type" : "boolean"
      }
    }
  },
