I use the relay to go to the detonation site, but always spawn mid air, fall, and die instantly. I've reloaded old saves, tried it with BoS and The Railroad, and the same thing happens. I can't progress anymore. What the hell, Bethesda??

Hey there. Just sent along a DM requesting a save file to help investigate. Thanks!

No problem at all. I'll do anything to help. I'll get that done for you as soon as I can.

Okay so I loaded it up a few more times then it spawned me on the floor below the roof where I needed to be but with all the walls and scenery glitched out and no way of getting to the roof. Reloaded again and it worked as it should and I finished the mission and get the achievement. Would you like me to still send my save file? If it helps others, I'm still up for sending it.

Yeah, if you don't mind. Couldn't hurt! Thanks.
