Used to be when I had a bunch of Aunt Irma's buffs in my tab I could use a few and the 25-stack I took from would go down as I used them, yet that stack would remain in the same position.
That was important, since I do not want to reduce several stacks - I could always just use the one stack and then go to the next.
Some months ago, whenever a buff was taken off a stack of 25, that stack of 25 would now be 24 or 23 as expected, but would appear way down in the icon listing - in other words, when I want to use a buff from a stack already used, I have to search for the used stack which changes position every time I log on.
Sorry if someone is gonna get upset but I have to say this type of problem is simply sloppy programming. It was and can be done properly but then it was ignored.
Please pay more attention to detail and please have more respect for your customers.
