This is such a common bug, really sorry we didn't make it clear enough

[nikolasleblanc]

Haha, yeah, this just happened to me too. Maybe an error message saying, "Did you open a document dummy?" :)

[robksawyer]

Or to be completely clear, maybe... "Hey dummy! Did you open a new document in Sketch?"

It's funny.
