How the hell do you fill water flasks at the surface? I haven't found a single damn way to do so and it's causing me to have a freak session because multiple things say you can, but as far as I can see, you friggin' CAN'T, and being lied to by games about their mechanics (namely, that I'm supposed to be able to do a thing, but I can't) wreaks HAVOC on my head, is it actually a straight up lie? Or am I just constantly missing the method despite checking everywhere that I can logic out might have a "fill flasks" button or anything similar?
