Water Purifier Bug - 27 Oct Nightly Build

I pulled an experimental build from 27 Oct when my previous game became corrupt. I’ve noticed this bug previously. When purifying water it’ll have a requirement of 1 battery/pill per unit of water, but then only use 1 battery/pill.

I can’t seem to replicate this one.

Maybe they already fixed it in the newer version?
I’m running curses version. Would give the full version but I’ve already deleted the folder. I’ll post again if it happens again.
