Guild point items are using incorrect calculations to compute the cost of buying the required number for cap when viewing stacks.
ie. Dark Bass for today:
[Singles]
NQ: 60 HQ: 0 Max: 2,160
Max = NQ x 36 (18,000 Gil)
Gil/Point: 8.33
[Stack]
NQ: 60 HQ: 0 Max: 2,160
Max = NQ x 36 (108,000 Gil)
Gil/Point: 50
Currently selling @ 3k/stack on Midgard, so should logically show (36 / 12) * 3k = 9k
Might only be applicable on fish since it seems most other GP items are unstackable.
