Considering the whole mess of bugs that are still in the game 8 months after release, I don't think you can really say "they find out about it and they fix it." They fix some things sure, but for every bug they manage to fix, there's about 20 others they ignore and another 2 or 3 that emerge from their latest "fix."
At this point, I'm just wondering why they don't reverse-engineer the Unofficial Skyrim Patch mod to apply to the consoles. Seems like it would save them a lot of money and headaches.
I don't know I don't work for Bethesda there will be one reason or another. But i'm not sure, i'm not a technical program designer perhaps there is something stopping them from doing it as I'm sure they don't want to be always fixing patches that we get ... for free, if they could have done that they probabily would have and saved themselves alot of time.
But either way, atleast they're attempting to do this. I'm sure alot of other companies just wouldn't bother with so many patches and such.
Sure enough alot of games don't have so many bugs but as people have said with a game as big as skyrim there are bound to be some problems, and atleast bethesda are trying to fix all the problems, and they are juggling around patches, dawnguard, designing future dlc and getting in their voice actors to read new things. So who knows what, Bethesda may have their hands full at this crucial point.
But again, i'm not sure. now i'm not backing them, I admit they could probabily do a few things better which i could easily point out..... about werewolves...... because I svck at anything else in regard. But none the less i'm thankful for what i've got.... even MORE thankful when i get Dawnguard so i will no longer feel insecure.
