I completed Molecular Level siding with the Minutemen, and built the teleporter in Sanctuary with Sturges.

I built it on a foundation, the scrapable house next to the workbench (the one in frot of, when facing the workbench)

However now Sturges doesn't move anymore.

He stands still on the road and I "lost" him as a settler. I can't give him orders through the workshop menu, he isn't even higlited and my settler count went from 9 to 8.

I can still talk with him though, but only to trade. In his inventory there is his gun, a bullet and the teleporter project.
