How do I fill up the water bottle? It hints me to go the waterfall at the top end of the area. However, when I have a person go there they say they have better things to do and need to help the woman in the tent first. That's what I'm trying to do! I've tried the three different people at the waterfall. I've tried dragging the water bottle on the river/waterfall in various areas with no effect. I can't do anything else til I help the woman in the tank!! HELP ME LOL!! Super frustrated.
