Got the quest and progressed it as usual, but when I reached the platform where the big Crux should spawn nothing happenend. I tired reloading the area, restarting the game, but that did nothing. Since the quest was still in the Exo Stranger's vendor menue I figured I could abandon it and restart it here, but it won't let me reacquire it since 'Quest already acquired'. Am I screwed now or can I somehow fix this on my own?
