Not a Bug Buying books

[DeletedUser]

Not sure if this is a bug are not.
Today I bought 3 books with coins (not the first time),bud I noticed that the books on the right
(buy 10 books for diamonds ) also changed from 10 to 7.
Sorry, don't know how to make a screenshot here.

Buying knowledge points (I believe those are the "books" you are referring to?) indeed updates the counter on the 'big package' deal on the right side of the screen: that deal fill up your knowledge points bar. As you can only have 10 knowledge points in that bar at any given time, the offer will indeed update to reflect already available knowledge points. It would be bad if you bought 10 knowledge points, but only ended up with 7, because you already had 3. All in all, this is not a bug, but a feature.
