I have a friend who fixes other people's coding for a living, I mean, that's not the total extent of his job, but when he joined, he pretty much spent his first 6 months doing exactly that before they realised that it would be much better to just have him to do it in the first place. It does actually take a lot of effort to find these bugs and so I'm not going to criticise them for perhaps not finding it immediately, after all, they have to identify the bug, then find out what causes it, then find a way to fix it, so the fact that it is being tested, ready for release makes me happy. The radio silence on the other hand is what I found disappointing. In my personal opinion, it is always better to keep people informed and to be honest, be humble and appreciate your players. That being said, at least they are going to fix it, unlike a lot of devs who have just abandoned their games after release and said a massive FU to their players.
