Story from when I was a noob:

So I finally venture off trying to find someplace other than where you start out at to live. I find this beautiful place with waterfall and I build a stone base. Then I a couple days in the game later I come in contact with this devil chicken man eating monster. I wasn't aware of how strong this chicken was and so I thought me and my level like 7 and 9 raptors could take it out.. well I soon realize I'm completely wrong and I run back to my base like an idiot. it starts destroying my STONE base that I had JUST FINISHED BUILDING not long ago. I'm just confused.. why can it destroy a stone base but not destroy STONES??
