There are technical problems. First fact is: not all that is reported as "bug" is "bug" indeed. Fact also is, they are working on them, several patches already have been out. Fact finally is the bugs are more present in the campaign. I do play the freestyle game only. And face much less bugs there. Others confirm this. The campaign, on the other hand, almost made me quit. Almost...

Thank god I mad up my mind, and I did not regret it.
Another fact is that after frequently reading the forums at Steam and Egosoft, I find that many people a.) just parrot the hating that swapped over the boards at the start, and b.) many people report as bugs what they have not understood in functionality, and do not know how to run correctly. The bug thus is lacking knowledge and experience (I initially fell a bit to that very early, too, the game makes it easy to walk into this trap since it does not give enough documentation on its features, and not always the kind of feedback that in the action would be appreciated). Both things now spread, living a life by themselves, it seems. That is not to say there are no technical bugs. There are, but much less than one get get an impression when reading the forum, I'd say.
Egosoft made some questionable design decisions, however, that complicate the handling, and that adds to people finding it difficult to learn how to do something - and then calling the lacking result a "bug". Let's face it: the documentation is lousy. I had so many questions that I needed to search for in the forums that I had to interrupt gameplay quite often. But mostly, I found answers. Some issues however indeed are bugs, it seems.
But I must admit: the game is much better than it's ruined reputation, and it is much less bug-ridden than many aggressive voices indicate. The early experience of one's own expectations not being met, currently has the momentum.
By what it offers in potential, it is brilliant.
That's why I keep on saying: do not scratch this one off your lists too early. Give it a recheck in some time, really. I play it all day and night long since release now. If it were really that much broken like the opinions in forums seem to indicate, not only wouldn't I have been motivated to do so,
but I also should have been unable to do so. But here I am, playing. Can't be that bad at all, then.
Egosoft acted stupidly, yes, and rushed it. Some design decisions are questionable. Interface ergonomics leave to be desired. But the game is much, really very much better than what the forums make you believe, or the Amazon feedback (Germany, England, US, they all give it 1-1.5 stars). That is undeserved, and more a media phenomenon with kind of an unstoppable self-dynamic now. And many kiddies howl to the moon while not knowing what they are talking about. Then there are those fools who complain about pushing everything to maximum settings, in an object-saturated environment like this DX9-game offers, and then complaining about getting low frames. That made me laughing already two weeks ago, when Assetto Corsa was released.
I hope Egosoft lives through this time, and stick with it afterward. Criticism is one thing - but the kind of attacks I have seen in recent days, is very different.
I have explored in a fast trip all systems, sectors and zones now. The universe is huge, and beautiful.
