Playing game in Solo mode(non-public) on PC, played the Eliminate mission by choosing mission from the Zariman Navigation option. After completing the objectives of eliminating all the Grineer and getting back to extraction elevator the mission would not extract. Only option was to Abort mission. Other objectives I completed during mission was eliminating the Void Angel, finding all feathers (voidplumes) as well as completing the Incarnon objective of 20 head shots to void angel for Felarx. Using unstuck command, falling off cliffs nor using the alternative Extractions travel bubble didn't help.
