 ## Description

 The library I'm using to access Telegram has some small bugs. One of those
 is the display of meaningless (because they are being acted accordingly upon)
 error messages. Those include:
-* `Exception in thread "pool-x-thread-y" java.lang.Error:
-java.nio.channels.ClosedChannelException`
 * Something containing `AUTH_ERROR`
 You can just ignore these messages.
