Bug while I'm playing.

What I expected to happen was...:
I don't know.

What actually happened was...:
I shot down a skeleton with my bow, he died, I went down to pick his loot and, while I'm going down, the game has crashed.

Steps to Reproduce:
1. First, I was in live on twitch.
2. I pushed "Escape" on my keyboard to see where I am in my achievements.
3. I saw: "Kill a skeleton [...] 50 meters.".
4. I crafted a bow.
5. I went outdoor of my place to find a skeleton.
6. I saw one not far from my position.
7. I tried to kill him with my arrows.
8. The three first, I missed him and, the fourth, I got him, a fifth and a last one to finish him.
9. I went down to pick his loot.
10. And, when I went down,.. The game has crashed.

Nota-Bene:
I'm french.
