It's honestly a really well polished game and I've only had a very small handful of bug encounters. Its less buggy than curent patches of FO4 and Skyrim
My biggest common Bethesda glitches so far was ONCE, one of the NPCs had the white squares attached to her hair and played miss sparkle for our conversation and then the occasional alien getting caught on geometry and then vibrating because the engine didn’t know what to do. Outside of that it’s been remarkably bug-free so far. Oh, I’m 30 hours in too!
Yeah, i found a couple of crates that decided to co exist in the same location as my most bethesda bug so far. I have had 1 quest fail to progress at one point but a quit out and load an earlier autosave fixed that.
Ironically I think BG3 is buggier than Starfield on release.
I've experienced a few instances of bethesda jank, but nothing game breaking or even requiring a reload in ~55 hours of play. Just silly things like bodies getting stuck in a ceiling after an explosion. My SO is playing BG3 and has been getting CTD's and other more egrigious bugs since hitting act 3.
