Translation:You must return to the headquarters immediately.
I wrote "You must return to the headquarters right away" (which is an appropriate answer according to the hint) and it marked it wrong. Wtf?
I was marked wrong for writing "You need to" instead of "You have to" -- is that legitimate for some reason, or just another example of the shaky English translations in this module?
The verb here is "need to" not "need". "Need to" carries more or less the same meaning as "must" or "have to".
