I am fairly certain that in the situation you describe, either one of two things would happen (I am not entirely sure which, but I am leaning toward the first):MatronDeWinter wrote:Pretty sure the remainder would just randomly appear in whatever container the item was you tried to drop the excess amount on. This should work for all items, the max stack of anything is 60,000. If I have 59000 feathers in a locked down box, and I drop 20000 feathers onto those 59000 it should make a new pile of 19000 in the same box and update the other pile to 60,000. Likewise this should work when dropping things onto the box, instead of on the actual item.
Thats how I remember it.
Either, your 59000 feathers would become 60000, and the 19000 additional feathers would fall to your feet,
Or, your 59000 feathers would remain 59000, and the full 20000 feathers would fall to your feet.
I am pretty sure that this mechanic (whichever one it was) was the same regardless of item type (gold, feathers, ore, root) and regardless of what container you were trying to put the items in (bank, or locked down box), provided that they would fit into the container weight-wise and item-count wise.
I think that the reason that this actually happened was that the remainder (either the 19k or the 20k) would, by default, returned to your backpack. Because of the weight constraints on the player, the item would then fall to the ground at his feet. So, in another example, if you had a pile of 59999 gold in your bank, and you tried to add a pile of 101, either 100 or 101 gold would be returned to your backpack (and would most likely not fall to your feet unless you already had 424 stones in your pack or something).
This would explain why it was always relatively large amounts of gold that were dropped usually 8k at least, and almost never some trivial stack of 600 or something.
As for the part about dragging the items into the container (rather than into a pre-existing stack), I can tell you for certain that it did not work the way you described. If you had 59000 feathers in a box and you dropped 20000 feathers into the box, you would have two piles of feathers in the box, but they would be 59000 and 20000, no question about that.
