How to reproduce:
1: Before Compy builds the iron mine for you, mine every single piece of copper, and destroy every single tree.
2: Place your copper and excess wood in the way of Compy building the iron mine, then simply follow his instructions.
3: Compy will destroy everything in his path, just to teach you how to build a mine.
I have a world download where I have removed every tree and copper, and it's ready to have you watch Compy destroy any chance of survival on this desolate alien planet: https://www.dropbox.com/s/3sscb3dig96ow ... z.zip?dl=0
