Miscellaneous: Items that stack but shouldn't until Velious

[Seltius]

So with this when velious is released(or patch time in timeline) will Antonian Javelins go back to being stackable? If so what will happen to the ones people have on characters that are still stacked that just don't list 20? On a character I have 5-10 stacks of Javelins still(was offline for the nerf) that when they were changed to non stacking look like a single one but they have 20 throws before they poof.
