don't think it's a bug...
i see it too, and it looks reasonable - comparing to other stores...
of course i like this change! )))
but on the other side, it cd mean that this is not the only change.
we need help of lower level players now to check if there are any other differences from what is stated in upgrades chart.
i can only see jenny & charlotte 5>6, and jack 4>5 still there.
but i have a suspiction that lower upgrades cd be changed, as well as luxury shop 2>3...

Hmm looking at your chart it does seem reasonable... I'll take it!
