Hello, I was wondering if the cost for items in the fishing event got overlooked or are incorrect?

I have spent 600 energy on instances for the Monthly event (Complete 60 plot instances) and ended up with only 72 credits. Now normally that seems fairly good, until you see that Basic Thread costs 100 points, Basic refine runes are 80. ect ect. So at the end of the event, I can end up with 7 Basic thread or 9 basic refine runes?

With no options to spend to even get more nets, this seems like perhaps someone made a mistake on the values this event. Maybe they added a zero to the end of all the costs by mistake?
