I can't fill my 2nd Canteen, it will only select the "first one". So if you're trying to get water for a friend, you can't. Not very realistic! :)
- Legacy ID
Are you doing this: When the canteen that is currently filled is in your hand slot hit the [X] at the top right of the hand slot in the inventory screen. Drag the empty canteen to your hand slot, then fill it.
Because it works fine for me, I'm unable to reproduce this bug.
Yes, when I dragged the 'empty' canteen to my hand, it just selected my '60%' canteen. Also if I dragged the icons onto the 'action bar' it would show 'both' being lit up, as if it was the same item. Even though I dragged 2 different items to the action bar.
Ontop of that, the action bar doesn't show proper "quality" of the icon, so I'm thinking the item dragged onto there, isn't actually the ID of the specific item you're dragging - but just a general ID of the item type you've dragged. Some major designing flaws going on here :P
I think the problem here is the "action bar" with identical items.
You can reproduce this by having 2 guns (1 with mag / 1 without mag) and put both in your "action bar".
When you swap via the "action bar" you will see that you always have the same gun.
