That bug doesn't affect your ability to play the game at all and also can be easily avoided or possibly not even encountered in the first place by some players. I know exactly the kinds of bugs mentioned in the comment above and I agree it used to be very bad to the point entire sections weren't playable, but it has been fixed since the newest version. Point is you can play the game now unlike before just don't expect everything to be 100% stable until a full release is available.
