Issue: Filling the water barrel via a waterskin bugs out, preventing filling of barrel with random water skins.
Repo: fill a number of water skins, place in water barrel. Right click placed water skin and select "fill barrel" On occasion a water barrel will instantly refill a water skin placed in the barrel after choosing fill barrel, thus preventing filling of barrel.
Notes: If player waits a few minutes, player may be able to fill barrel again with previously bugged water skin.
