you know how the hatch creature eats resources during the night. well they stick around a little while after everyone wakes up and I saw it eat a duplicant as he was running on the power wheel. and the "-resource" text appeared. I only discovered this after losing two Duplicants before him and not having a clue as to their fate. The hatch also wasn't hostile to the duplicants when they passed by it so I thought I would keep it around to produce a little coal for me. (little did I know it was a silent killer).
