"그들은 온 후에 우리 파티했어요."

Translation: After they came we partied.

That's frustating that "We partied after they came" is not accepted

The whole course is a mess. English can move parts of sentences around very easily and have an identical meaning.

Same for Korean. Duolingo really needs some intelligent language processing engine to parse these. Perhaps the development team needs an A.I. or machine learning expert.

[jjd27]

Why is there no particle after 우리? Surely this is the subject of the sentence so should be followed by 는 or 가...?

[crossmr]

A lack of competence

[Kemushi_]

There's a function to report that, use it instead of complaining

온 is only translated as " whole " in the hints.
