[Unverified] Tax on unlimited shops [Buying]

[netherfoam]

As you suggested i made some "admin shop", now i have another problem. No idea if its a bug or its supposed to be like that but when i set a shop to unlimited tax are not added to tax account but they are subtract to price (tryied while selling with another account ofc).

example to explain better just to be sure, my english is bad sorry ;)

BALANCES: admin: 100 player: 100 tax: 0

player sell item to admin shop unlimited for 10$

NEW BALANCES: admin: 100 <- RIGHT, no change if unlimited shop | player: 109.5 <- RIGHT, 10$-tax | tax: 0 <- WRONG, still 0, must be 0.5 |

Is that a bug? How i can fix that?
