Correct answers initially marked right, but later wrong
I noticed a problem while doing timed practice sessions in Duolingo's English to Spanish course. While translating from English to Spanish, there will often be two correct answers. Sometimes, when I select both correct answers, the system acknowledges my response and gives me a point, but at the end of the session, I'll only have 19 out of 20 marked as correct. If I review my answers at this point, the response Duolingo originally marked correct is now marked wrong!
This seems to happen most often when two answers are identical and only differ by a pronoun. For example:
"Yo como manazanas." "Como manzanas."
If I select both of these answers, there's a significant chance I'll receive points at first, but have them taken away by the end of the practice session. Has anyone else noticed this behavior? It definitely seems like a bug.
Same bug here.
I had those two multiple choice questions (that I answered correctly):
But the review of my answers displays them as wrong:
I submitted a Bug Report about it.
Nope, no feedback yet... and it just happened to me again too.
EDIT: Interestingly, if you only select the answer that it wouldn't eventually mark wrong (the one with the personal pronoun), it marks your response wrong immediately, but still gives you the point. This is definitely a bug that ought to be fixed.
Yes ... In timed practice when confronted with two correct Spanish answers that differ only in whether the pronoun is dropped or not, I sometimes find myself having to choose between a) answering correctly in order to get the extra time now, but losing the point, and b) leaving out the shorter answer, getting marked wrong and penalised for time now but still scoring the point!
I notice that in Spanish this is the only type of multiple-choice question where one answer is inconsistently marked wrong. If the two correct answers contain synonyms (e.g. carro vs coche vs auto) or other alternatives besides dropping of the pronoun, there is no problem.
I also reported this bug a few months ago.
Yes, thank you. I did see that and reacted lower in the thread. I don't know how to make a direct link to my comments. How did you find the right comment number for your link?
And I'm so used to it now to pick the answer that will be marked correct eventually. However it is inconvenient with timed practice because you don't get the extra time for a correct answer.

Either in mail notification or going into the javaconsole to find it... ;)
