Seems I'm having a bug no one else is having, as I can't find any info anywhere about it. I locate the Cab in Wellsprings, scan it, talk with it, then I have to damage it so Delamain can take over. After causing enough damage to shut the cab down, I get two calls. First from the corrupted Delamain, then a second from the real Delamain. The issue is, the mission says "Talk to Delamain", but when I answer his call, nothing happens. He doesn't say a word, then after a second he just hangs up. But the mission still says "Talk to Delamain". I try calling him back but he doesn't pick up, and the mission will not progress further. I've tried reloading my game and redoing the mission, but the results are the same.
