When buying amity items there is too much amity consumption.

Bug Name:

When buying amity items there is too much amity consumption.​

Bug Description:

When buying a design with merv, normally the amity consumption should be 400, but it has increased to 518.
I'm not sure if it's because I'm wearing a calpheon noble dress
(but that's only amity+15%, shouldn't increase purchase cost)

Confirmed that the amity bonus will also increase the purchase consumption, I took off all the clothes and only the tent buff(amity gain +10%)was left, and the purchase consumption was reduced to 407.​
