I have to admit I have also noticed the discrepancy of the infocard and this event. I mean what's the point of rebuilding the docking ring if everyone is just desperately trying to leave the soon-to-be-snowball planet?
This event seems a bit gamey, as if someone is trying to shoehorn the last remnants of the playerbase (which is mainly Zoners, Freelancer traders and Core casuals at this point, with some Hessians and odd Corsairs ) into doing someting meaningful.
