That mission has not been the daily yet and supposedly the 777th day was yesterday. The mission was the iron tomb which is a RoI mission but no one found anything. We will see what happens when that mission comes up but I have my doubts. I figure that area people were glitching into is just a duplicate of the ketch on Venus where u go to kill draksis as that ship is just a copy of it. I have mentioned that before and someone said it had the same layout and had house of winter banners around (Venus fallen). The only weird thing was that it had its own name. Either way, we won't know until it happens. Bungie may be holding off on letting it be the daily until they want to release the time gate on some new and exciting thing to go after and we have proven they can keep things hidden from us in the armoury and kiosks so who knows what it could be.
