I got quite far in the Brachius Mining Facility mission to fix my ship. But after I picked up the second note from a chest - "Letheia Corporation Guidelines" - I found it completely impossible to progress further. That's because all doors were LOCKED - as in, they were closed and refused to open. And, yes, I double and triple-checked for any other possible route to take. There were none. I'm uninstalling, if only to see if this clears up this issue.

Also, that was the second time I attempted this mission. The first time I entered the base, then exited to see of there was anything interesting on the moon's surface, then tried to re-enter the base. But, the base's doors were closed and refused open...
