Exploit the Hatches to work all the day

Yea, I do this myself.  I don't know if it's a bug or intended.  Just trap hatches in tiles and they'll never sleep.  They'll just work all day.  

they burrow in soft soil like coal, dirt sand. they seem to die on tiles all around so you need hard surface but not full tile. also eats more if cant move at all just trap him on obsidian/granite
