hi again, i posted here like an hour ago asking about the secret ending and i am now clearing out all the NERO checkpoint and as the title says im on the Chemult College checkpoint, i cannot find the fuse for one of the NERO buildings, i tried googling but the fuse is not where the guide said it would be. i figured it was a bug so i restarted my game but its still not there and theres no tracking thing that pops up either and now i have no idea what to do.

Edit: just checked a youtube video for where to find the fuse, the person playing found it in a closed box and looted it but when i went to that box it was already opened and empty, what the hell do i do now?
