I have this problem with this Strife conversation. The shopkeeper says what he is supposed to and it takes the money from the inventory however it will never give the player the item. Tried it with Zdoom and it has the same problem. It has to be a problem with the script.

actor = 1; //Shopkeeper

name = "Shopkeeper";
dialog = "Hello, what can I do for you?";

text = "A drink";
cost
{
item = 4; //Money
amount = 1;
}
displaycost = true;
yesmessage = "Purchased a Drink";
nomessage = "No money, no buisness.";
giveitem = 3; //Small Drink
nextpage = 1;
}
}

Everything works and will even say "Purchased a drink" but you won't get the item.
