Description

The last event is:

  "origin_server_ts": 1517724841728,
  "sender": "@travis:t2l.io",
  "event_id": "$1517724841827kWspz:t2l.io",
  "unsigned": {
    "prev_content": {
      "history_visibility": "shared"
    },
    "prev_sender": "@travis:t2l.io",
    "replaces_state": "$1517724826825LQbiB:t2l.io",
    "age": 3594
  },
  "state_key": "",
  "content": {},
  "type": "m.room.history_visibility",
  "room_id": "!WrHLMbqacufOBWIxwC:t2l.io"
}

I didn't actually change the history visibility in my attempt to change the room settings. I did however change other settings in the room:

1. Open room settings
2. Set join rule to something else (in my case, anyone including guests)
3. Add an alias
4. Save the settings

If the save is quick enough, it's possible to get the visibility to be set to unknown values.
