We author a lot of of our forms on google doc / slack so that the team can collaborate on it. Then when we're done, we copy paste it into mailmodo. Sometimes, implicit special characters get copy-pasted (like /n), which we can't see in the form to realise this has happened. But then our journey execution fails because the option chosen by the user has a "\n" at the end, but we've based our journey on the text without the \n.
