"Bhí an léachtóir ag obair aréir san ollscoil."
Translation:The lecturer was working last night in the university.
the lecturer was working in the university last night was rejected ! makes no sense at all!!
It's because Duolingo is a real stickler for translating things exactly in the order they're listed, even if another sentence makes sense.
but they're fixing these kinds of errors right? coz sometimes the sentences do not make sense! haha
