But I don't understand this. It took six months to develop this patch. There was external testing with players. Couldn't you fix the bugs without generating new ones? I don't understand.
Given the sheer size of the game and the substantial changes they implemented with patch 8, I'm surprised there aren't more bugs.
I would imagine that debugging a game of this scope can be a nightmare - especially if you're adding/changing as much stuff as they have with this latest update. Even if they know about a bug, it's probably not as simple as clicking a "fix that crap"-button for them. Changing one thing to fix a bug might cause other elements/mechanics of the game to glitch out and/or they might not even know initially what exactly causes certain bugged behavior and thus have to do a deep dive into the code to find that out.
