Previously stacking quantity of some items was changed. We had 3 waves of such stacking changes. You can find the details in these 3 threads: Stacking Changes Part 1 and Stacking Changes Part 2 and Stacking Changes Part 3.
As we received multiple requests for additional changes, we are starting this thread. If you want to increase stacks on some items, post it in the following form:
<Item name> (and, if possible, ID from archeagedatabase): <current stack> → <new stack>.
<Short explanation on why it needs to be increased and why to this level>.
Make sure not to post it like "all poisons" or so on as in that case we'll simply ignore it and make no change.
If you have the doubts regarding the item name or ID, you can search for it here: http://archeagedatabase.net/
