:w00t: I think I solved:
When in download list file is 2x then it update wrong package.
I give example:
I download package abc before 1 month and keep in download list.
When I download other with same name abc today it thinks it is package from before and update earlier item in list.
But it must update item of today.
So it not check correctly what item it extract.
So it must not only check name but also id or something to update correct list item.
