That was actually a smart hack, because Xbox had limited memory.
If you wanted to make a comparison, it would the Morrowind bug that if you did specific things in hour 15, it'll definitely cause your game to crash in hour 120.
It'd be more news-worthy if Bethesda released a game that DIDN'T start crashing more the longer you played. I remember dealing with this in Fallout 3. Here we are, 15 years later...
I was at around 55 hrs during endgame, which was finishing the main story line after doing most of the side quests. I think I had 1 main base with 10 - 20 buildings and equipment. I was playing on a series S. I am boggled you didn’t have many crashes, I’ve seen hundreds of reports of similar issues when I was trying to figure out what was going on.
