I'm having this problem too and I reported it too. But I'm curious now, it seems that this is not the first tine this bug appears, so why can't Oasis repair it, but can remove the special ninja pack from naruto's ramen in a instance?

I don't know why is the developer so useless and incapable of resolving this problem. The easiest way is just to add one more link, which allow us to give up a Sakura's mission and accept a new one.
