getting another zeta weapon need help

[Hasrat]

They've already started. They're at zeta. The last step in the process. They're saying NPC for mahatmas isn't where he should be.

Just checked for myself, and he's still standing there for me, and I'm not even at that stage for my second one. If you're certain you're looking in the right spot in the settlement (there's not that many people to talk to, so I figure you probably aren't just not seeing him), you might try logging out and back in, to see if the game loads him in correctly.
