I've searched and searched for the solution to this, but in "Biomass" there's a bit where you get in a crane and have to pull three rods up while a big flesh blob shoots acid at you. Okay, that's easy enough. But once I've done that, I can't find any way to get out of the crane. There's two green areas on the crane's... radar?... so I thought maybe move to one of those and a prompt would come up. Nothing. I've pressed every button and can't get Artyom to just GET OUT of the dang crane. Is this a bug?

So I've watched some playthroughs and it looks like a prompt is supposed to appear. I've tried literally all the keys on my keyboard and all the buttons on my mouse and nothing will get me out of the crane. I've reloaded the checkpoint and done the crane sequence over again. Nothing helps. Seems like the end of the line for me.
