Okay, so for context, the Bus Depot loading screen you're all seeing here is located in the BO2 Microsoft Store version of the game (and the loading screen for it was meant for Bus Depot Grief), accessible by digging through the files. Along with it are the scrapped BO2 Chronicles texture files that exist (yes, the SMR Wallbuy Chauk drawing does exist in the BO2 MS Store Files of that version).
