Game does not recognize water in containers, tried using both a canteen and a plastic bottle filled with water, and the water doesn’t appear in the list of materials.
Even when standing next to an infinite water source, water doesn’t show up in the materials list.
EDIT: standing next to a toilet with water in it however, does work.
It’s a bug related to infinite water sources. We got it identified and so should be fixed soon.
You can avoid this bug by not having any finite water when near odd number of infinite water sources or by having some water and being near even number of infinite sources.
