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).
Keep the hatch alive and have your duplicants perform stationary tasks like running the hamster wheel or making food after everyone wakes up. that is ussually when the hatch is still around after morning. I also had bare rock next to my tiles that he would go and burrow each day.
