Usually it seems that every slide position is a 1 stack size, but when requesting items with a stack size of 200 (bullets, cables), the slide starts full left (at 0 position) instead of at first tick.
Steps to reproduce:
- open inventory
- click on an empty personal logistic slot
- select an item with stack size = 200 (cables, bullets)
- note the position of the slide
as an example
- select red cable (stack size = 200) or plastic (stack size = 100) -> slide is in wrong position
it also happens if, instead of clicking on an empty slot, you drag an item from the inventory into the personal logistic slot - select green cable (stack size = 200) ->slide is in right position
