I was finally able to get off planet. I did all the quests on H-047c except The Remnant Tiller. I completed Vetra's loyalty mission and left the last bubble and moved into an open area. I pressed T and continued to hold it down, but nothing happened. The Hazardous conditions detected. Extraction impossible was at the top. When I let T go, the Tempest [T] Extraction in progress came up, pressing the T immediately again didn't function and no extraction ever happened.
I decided the only thing I could do was The Remnant Tiller quest. Since it always kills me when I go down the gravity well and kicks me outside without the Nomad, I decided to run to the ship. Normally if you fast travel on foot, you will end up next to the Forward Station you selected with the Nomad next to you. On this planet/asteroid when you fast travel on foot you end up in the Nomad. So I jumped down the Gravity Well, died, ended up outside, then my companions and I ran all the way across the map to the Tempest and entered her normally.
The only problems are right now I can't complete The Remnant Tiller Quest and if I was able to go down the gravity well without dying, I would still be stuck on the planet.
The interesting thing is when you finish Vetra's loyalty quest, you get on Sid's transport and take off. But, you end up in the Nomad!
