What is wrong with "Pupas multas emo"?
Yeah, it happens to me constantly. Since Latin is a language with a syntax not based on words order, this type of error is very, very common. But I think over time they'll fix that.
Why can't it be "Emo multas pupas"?
Probably just do not yet accept that word order, report it should it happen again.
