[Yuhaney]

if the answer is "No" I don't need further help, under no circumstances explain anything, just write "No, it is not a bug" in that case

edit: it's not a bug

You forgot to write 'No'!

You said: 'just write "No, it is not a bug" ', and you writed 'it's not a bug', so you forgot to write 'No'.

And answer to your question is: No, it is not a bug.
