When i am holding a Canteen or Waterbottle in Hand and choose the Option "Drink All", it plays the drinking Animation, but doesn't end the Action itself properly. I am left with the Fill-State at the same Level it was before and using the Canteen or Waterbottle again only offers the Option "Cancel Action".
Using the Option "Drink" until it is empty, does work.
Might be this only occurs, when a Player is holding a Canteen AND a Waterbottle in the Inventory, not sure though.
