The problem happened again (had a similar one, two weeks ago).
During the night, at one moment I received 4 notifications. I guess the bot was hung up at that moment and decided to duplicate the answers. I'm not trying to rebuke you (by no means think that). I am only trying to help, find the problem and notify you about it.
Tried deleting the bot again/re-entering it = can't tell the result yet. If the problem shows up again, then it didn't work for me. I can still give feedback in the future if needed.
P.S. A bot is convenient + practical. Thanks for taking care of this and optimizing it as much as possible.
