Why is the cost of medium houses now DOUBLE than how it was for FC housing??

[Hammerfist]

When FC housing came out in 2.1, medium houses and large houses costed rispectively 3.75x and 12.5x more than a small house (on my server the starting prices for each size were 20kk, 70kk and 250kk): while prices went down in time, those multipliers always remained costant.

But now, medium houses and large houses cost rispectively 7x and 17.5x more than a small house (on my server the prices are 4kk, 30kk and 70kk), which means that the price for medium houses has actually been doubled.

WHY???

Good thing that, unlike 2.1, small houses have now an extra floor and that Yoshida said that personal housing prices will be "far more affordable"...
