I purchased a game which I believed was created by competant people. Why on earth do I need to send them a save game to enjoy my purchase? If I continue to have these types of problems, I see no sense in continuing this game.
To be fair to them, not many companies would offer to fix it for you, especially not with such a quick turnaround. Most, if they answered at all, would simply tell you to start a new game or make some vague and unhelpful comment about your PC being faulty.
Software has bugs; large projects can have lots of them. They're an unfortunate fact of life. In my experience, the key difference is really how seriously the problems are taken by the developers: in my experience, Larian have been first rate in this regard. If you want to see
serious bugs and generally bad QA with what can only be seen as a laissez-faire attitude to fixing stuff (to put it politely) look at Bethesda or a significant number of other major developers. Are Larian perfect? No, but they've been a lot more receptive and helpful than I've seen elsewhere.
