I'm using Item Scroller mod, and when I scroll wheel down the animation works, but when I scroll wheel up the animation doesn't work. Thanks.

Thanks for reporting, I already know this. This happens due to how the mod detects changes in the inventory. I'm currently rewriting the whole dectetion system and this should fix this issue.

#19 should be fixed with this update
