^{I honestly don't know why this changed, guess it's another weird bug that this league seems to be riddled of.}

You used to be able to hold ctrl + shift to buy a full stack of a currency from Lani, and if you couldn't buy a full stack, she'd sell you as many as you could afford in one go.

Now, for some reason, you can only buy a whole full stack, otherwise you get a "you don't have enough currency" message.
