People like to give Bethesda a hard time for the bugs in Fallout, but I have a suspicion it’s not just them. I think the Fallout franchise is cursed. I played the originals when they were new, and… well, let me give you an example.
In Fallout 2 (published by Interplay way back in 1998, for reference), you can obtain a car that serves as a combination fast-travel system and storage locker. The interface for using it isn’t the friendliest, and you can actually lose it permanently if you park it in the wrong spot, since random encounter maps despawn, but all that’s par for the course for CRPGs of its era.
What isn’t par for the course is that sometimes the back half of the car spawns in a completely different location from front half of the car. You’ll enter a map and find yourself standing beside… half a car. Each half is still fully functional if you can find the blasted thing (i.e., the front half can still be driven away, and the back half can still be accessed for storage), but they’re otherwise completely decoupled.
And that’s not even the weirdest bug afflicting the car in particular, let alone the rest of the game!
