Generation Zero destroyed my base

I started the mission on the mountain “Tyloveden” and I made a base there and then I closed the app and then when I loaded back in the game I didn’t have a base on the mountain anymore. Tell me why it’s gone, i didn’t even get my supplies back on doing that mission

It’s a known bug since there is the new base building intro mission.
It should be fixed in (hopefully) the next update.
