Diplomatic Immunity (misprint?)

By Meier, in Twilight Imperium 3rd Edition

This card is played as an action and states:

Choose a system in which you have at least one spaceship. Only you may activate the chosen system this turn.

Should this effect continue for the entire round (and not just a turn as written)? As written the card is quite limited.

Thanks

Correct. I submitted a rules query about that card myself and the answer I got was that it should read "round" and not "turn".

Thanks for the quick response. I couldnt find any clarification here or on BGG. I called it right.. lost the battle.. but called it right ..
