Fallout games have never really been put together particularly well, but that's what gives them a lot of their charm. Would Fallout New Vegas really be the same game if Doc Brown's head didn't creepily spin around from time to time, or if bodies didn't clip into the ground slightly and result in a horribly malformed ragdoll of a human being? Basically, they're very buggy, which makes the fact that Fallout 3's sunlight has been secretly broken ever since launch not all that surprising.
First posted to the Fallout subreddit by user JBozART, it turns out that a minor error in Fallout 3's coding has meant that the sunlight in the game has actually been pointing in the wrong direction ever since the game was released back in 2008. It's explained that a simple missing "-" in the game's coding essentially meant that the sunlight's y-axis wasn't inverted as originally intended, and that the sunlight has been out of line this entire time.
Of course, when you're traveling a Wasteland as inhospitable as Fallout 3's, you don't exactly have the time to ponder whether the sunlight is actually behaving as it should, hence why it's taken so long for this little coding error to be found. If you're that distraught about it and can no longer play Fallout 3 having gained this cursed knowledge, you'll be pleased to know that a mod has already been released by creator WallSoGB on Nexus Mods. Just be aware that there's a possibility you may struggle to actually get in there as the site has seen a lot of traffic following the release of the Fallout TV show.
With this discovery, that's another weird little bug found in a Fallout game that we can add to the books. What with the older games being very janky, they do have a history of peculiar little annoyances that were simply never fixed. For example, one Reddit user points out that this is kind of like the infamously broken In Shining Armor perk in Fallout New Vegas.
That was also an issue with the coding, in which Obsidian forgot
