Hello at the moment I have a problem with Colyseus "Argument exception: An element with the same key already exist in the dictionary" at line 214 in Client.cs , the logs show that I left a room properly but apparently this.rooms of client.cs did not delete the key in the dictionary.
(It happens when I want to change rooms, I leave the room in progress then I join a new room, moreover the error does not trigger often and is rather random)
Thanks for help
