It would take a team of engineers and it would take time to literally turn back the clock to X time in the past. And why do I say this? The game software has, most likely, undergone at least thousands and probably tens of thousands of builds. The amount of storage necessary to keep all those builds for 13+ years is incredibly huge; and while storage is cheaper than ever, the game was started 13 years ago and it's extremely unlikely they planned for this. At most, they probably keep 2-3 years worth of builds, because they might need them to revert a code change that caused a bug or similar.
