είχαμε φύγει όλοι μαζί was marked wrong - why?
I think that means " We had left" rather than we had gone.
Είχαμε φύγει όλοι μαζί is correct I wrote that DL marked it right
I.Schmidt1 --DL said that answer was correct (2/21/2018).
Is Eμείς είχαμε πάει όλες μαζί actually wrong or just not yet included?
You're right. We didn't have "Eμείς είχαμε πάει όλες μαζί." It's added now, many thanks. And thanks for the REPORT, it's really important.
it is the same!
