[W: 0.2.363 Alpha 2] Stacking overflow error

[Howeln]

Version Found - alpha 2, windows.  Two different computers.  Windows 7 and 8

Title - When colonists over stack, material is lost.

Summary - Colonists when dropping off material, if they drop in the same spot as a previous stack, the material overrun is what will be left.  i.e. Silver stack of 56, colonist drops off 57, 38 is left over.  56+57=113  => 113-75=38  Reproduced for food (potatoes) and silver.

Steps to Reproduce -
1. start new game
2. erase all zones (I did this to reproduce to force observing the error)
3. add in one zone, 5 spots, silver only.
4. allow colonists to haul silver.
5. clicking on colonist shows where they path ends up, if on another pile....
6. observe what # is on the ground, # picked up, and amount in stock piles.
*** note: this assumes one, the total (pile amount and colonist hauling amount) is greater than 75, and the colonist is not hauling 75.
7. Note how much is in pile, what colonist is caring, and how much is left over when they drop the stuff.

Expected Results - stack total goes to 75, and the colonist makes another pile...or adds to another pile

Actual Results - Loose 75 material, and end up with remainder.  56+57=113  => 113-75=38 the amount left in the pile.

Notes - At first I did not notice this with all the activity, I inadvertently caught it last night as I was looking at food qty, to see how much I had, and was amazed to see the summary amount lower than it was.  I assumed maybe they ate some, but with 3 colonists, having 75 food disappear was a bit of a surprise.  took special note to watch today with silver.

I created a new game to show example of error.  colonist is carrying 26 units, to drop off on 57 units, to end up with 8 units in the stack.

On closer examination, I find that there is a faint 75 under the 8.  The total sum count is correct, and the 75 is still there if I remove the stockpile, and create a new one.

So, a confusing bug, but not a critical error.

So, I just thought, maybe this isn't a bug, and we can stack multiple piles in one spot.....nope.

Once there is 75....or more, the colonists will not stack more on that spot.  Took attached save, removed stockpile, created one space and they only put two piles for the 75+26
