The game crashed and an achievement unlocked. That's . . . awesome. This game is great. Really like the sense of humor. Just got the horse armor item. That was pretty funny too.
That is definitely better than some game companies out there. Some companies can't be bothered with game issues at all such as Nintendo they don't update there games whatsoever.
On top of that, there were a couple of builds of the game shortly after release that were, shall we say, somewhat notorious for crashing for no discernable reason. So they added this to both take the sting away and poke some fun at themselves, and give their beta testers something to chuckle about.
