What you gonna do?
Change that ball to item?
Yes, if the quest isn't completed and is reported (as i described;p ) we can apply the actual reward. It's just that it doesn't always happen, some storylines' bugs are being fixed, new storylines are being applied. And if players don't report on time,it's not much fun :X
Now probably, someone will ask "Why we don't fix it, and avoid all this..", well there are lots of things that we are working on at this moment, trust me our programmers are working on fixing all kinds of bugs,and in the same time they are focused on new stuffs with the idea this game to become better and more interesting for you.
Edit: I like that red ball btw
