I've lost my companion Nick Valentine after completing misssion Dangerous Minds and starting Glowing Sea. I sent him to Sanctuary, but I can't find him there. I tried waiting for 24 hours and ringing a bell. I also checked his agency, Piper's office and Memory Den. Please help.

Same. I lost another companion however. The settlement I sent them two says there's one inhabitant but I can't find them no matter what I do. I think the only solution is for Bethesda to patch it or rig a global summoning system.
