Expected behavior

When the bot is removed from the room, function Room.find() shouldn't find the room.

Actual behavior

When the bot is removed from the room, function Room.find() shouldn't find the room.

Steps to reproduce the behavior (and fixes, if any)

1. Trying the following code

.on('login'	  , async user => {
  log.info('Bot', `${user.name()} logined`)
  bot.say('Wechaty login')
  setTimeout (async function(){ 
    await testRoom()
  }, 10 * 1000)

  setTimeout (async function(){ 
    await testRoom()
  }, 200 * 1000)
})

async function testRoom() {
  const room = await Room.find({topic:'呵呵呵呵'})
  if (room) {
    room.refresh()
    console.log('========find the room ===========')
    console.log(room)
  } else {
    console.log('========cannot find the room==========')
  }
}

When running the first function await testRoom(), the bot in the room, all works well.

Then I removed the bot from the room.

When running the second function await testRoom(), the bot isn't in the room, and I check the web weixin, the bot isn't in the room, but it still can find the room, all the data are same as the first one.

2. Relogin with the existed session using the code above

It still can find the room, but the memberList is null.

log as follows:

It's because the WebWechat has cached that. I guess you can also find that room in your web browser?

After the bot was removed from the room, Wechaty (or puppet) should call puppet.roomPayloadDirty(roomId) to clean the cache. (after wechaty@0.18)
