So i may have fucked up. I have 15h on subnautica on this particular run which is also my first one. I decided i wanted to make a base in the lost river so i didnt have to travel all the time. I parked my seamoth and started building my base. I finished my base, saved the game and got outside where my seamoth was nowhere to be found. It somehow broke or a glitch happened idk. But now im stuck in 1500m or more under the shore and in the lost river. I dont know how to get out now since i cant build a vehicle bay underground. I thought of stacking up on bladder fush and trying to survive but i dont know if thats gonna work. Anyone have any ideas? I really dont wanna start another run.
