Yes,minor spoiler but I was made smelly at one point, I was curious so used a thing of water to make everything wet, this stopped the effect. Probably could have gone through a river too. That made me curious there was a bad substance on the ground, I shattered water again and it made it passable. Now this sounds simple but I'm programming terms it's the same action interacting that changes different systems (in place hazard and character modifier). That alone could create small bugs when interacting with different modifiers, items and NPCs. For the most part someone wouldn't run into a quarter of the bugs they post (even a quarter is high) but someone will and it's awesome they are being patched.

Personally I've played about 20 hours since release, the only bug I had was when I was playing on hotfix 4 before they fixed that hotfix. It sounds worse than it was, since it was a compiler issue. I'm sure others aren't as lucky but even 10000 bugs isn't bad when it's a rare and edge cases. But with probability you get more players (and this game seemed to sell very well) and the weird bugs that even beta testers didn't find will come up.

Larian is actually a pretty large studio at this point.
