SoO Textures, datamining potential for 15th wish

I heard somewhere that it was possible to go into the game files (?), and look at all the textures in the game, and that that was how the 10th wish was originally found, before the actual location of it was found.

If this actually works, could someone check the textures once SoO launches, because there has been implications of the raid interfering with the dreaming city, from the ascendant looking area in the SoO trailer to the actual raid, killing a cabal corrupted by an ascendant hive relic.

Please forgive me if this isn’t actually a thing.
