The problem with the crash reports (that is, the bugs involving crashing games and an actual inability to play, not in-game weirdness like the 5-employee bug) is that they are the kind of bugs that affect some users with some setups, but not other users with other setup, and finding the common thread in order to identify the actual cause of the bug is a lot harder than it looks at a glance. Then you have to find a solution that doesn't cause its own issues elsewhere, implement it, and try to test it. And even with a lot of testing, you will usually find out that solving problem X for the users it affected now mean that problem Y affect a whole new group of user.
I get - very personally, I've been there - how frustrating it is when you're one of the users affected. But that doesn't mean it,s an easily solved situation.
