Well, thats one side of the argument. There are at least 3 crash bugs that I'm aware off. The reinforcement+wooden wall crash is well enough documented.

Also it seems players using intel chips experience a relatively stable game whereas AMD owners often complain of occasional or even regular unexplained crashes.

As for bugs I would not consider them rare but abundant. Just check the bug thread to get the idea. Perhaps not game breaking but definately frustrating.
