Or... they left it there on purpose, so that we would find out about this and there may be something more interesting behind all this ;p

BTW I'm pretty sure it isn't supposed to show bomb sprites. Maybe an ambient sound event can make it load different sprites (probably only if it's possible to get this event out of an MCE)?? If there is a way to view the correct sprite it may give us a clue on what the Springcord was meant to do.
