I facepalmed when I saw that sentence #-o . Inflation is part of the economy, my Granddad once told me a story that he bought a house for ~8000 gulden (which is around 4000 Euro these days). Ahh but inflation in real economies happens over very long periods, not over the space of one year and is normally not so easily identifiable by a change in the game (in this case), for instance look at the Abyssal Whip, around June when the PK changes were implemented the price has risen and not stopped since.
