Editing Textures not Working

[RelsyTines6282]

I wanted to change the textures of BBCCS 1 Year Anniversary, So I made my textures and loaded my new ones and saved and replaced the "sharedassets2.assets" file. But when I loaded up the game... The Textures were not changed at all... I exported the textures again to find that they were all reverted back to the Original Textures... This is not good and I want this bug fixed immediately.
