Alright, call me crazy but has this window always glowed like this? I haven't played BO6 Zombies in a while and on Liberty Falls on the bank roof, I spotted this glowing window. Now I've ran this map hundred of times but never spotted this before, has this been added in recently?

In the image I've zoomed into the window, it's on the right hand side. I'm assuming it's part of a side Easter egg or something? If anyone can fill me in, I'll be grateful
