I used to think the Bethesda glitches were cute too until 76 came out.
I enjoyed Fallout 76, but I also ignored it until something like three years after release, at which point it was in a decent state.
It wasn't Fallout 5, which is what I really wanted, but I got my money's worth out of it.
Only bug I hit that was kind of obnoxious was the occasional inability to pick up an item from a corpse, where one would have to look away from the corpse and then back. While being a bit immersion-breaking, it was also pretty easy to work around.
Honestly, the whole Fallout series has been pretty buggy, starting with Fallout 1, but still, a good series. Some of it just comes from the complexity of having a bunch of scripts running that can interact in odd ways in a relatively free-form world.
One of my bigger wants for Fallout 5 is easier diagnosing of problems with mods and trying to be more-robust against such problems. Maybe produce more-foolproof API functionality for common script tasks or something.
