Game Mechanics: Losing Stacked items

[Striiker]

I am sure that this is known but wanted to post it anyway.
If I loot anything which can be stacked, I lose all of my current stacked items in my inventory. This happened with Gnoll Teeth (which REALLY sucks!) and bone chips (sucks again because I had to run off hunting skeletons instead of grouping).
This problem extends to selling stacked items to merchants. Generally, a single item remains in inventory which can't be sold. The ghost item needs to be destroyed. Also, if you attempt to sell the ghost item, you can't click on anything such as selling or to open a mechant window again. The solution to this (oddly enough) is to jump which then allows one to right click on the merchant.
This is a serious bug, particularly for the new people joining the server who don't know what's happening and also for those of us who, out of habit right click on items to loot (thus losing the current stack of items in inventory).
Any estimate for when this can be fixed? Thanks!!
