I'm not sure how long this has been going on because I haven't played in a while, but I'm having an issue with the current extraction menu. Basically I accidentally hit X (on xbox) right as the extraction menu comes up on endless missions and I am immediately returned to orbit.
This primarily a console issue seeing as our limited control options can lead to frequent use of the extract button. In my case I use x for slide/roll so this has happened to me several times. I finally posted it about it after being kicked out of arbitration after just one phase.
