ed-e dissappeared on me, i still have his perk, and when i tried to do the quest with rex it says i have to get rid of him first, but he is invisible/non existant. this is on non hardcoe more so hes not dead. I tried quick traveling but he still doesnt show up. I tried going back to primm thinking he glitched there but he wasnt where he returns to... so now what?
I lost Ed-e once and freaked out. Went back to Primm to look for him. He wasn't in the Mojave Express. Then I wondered if it took traveling time for him to get back. So I used Wait for 2 or 3 days game time, went in the shop and he was there.
Turns out if a companion heads 'home' they don't do it instantly, and if you walk or fast travel there you will always beat them back. So wait outside in Primm for 24 hours at a time, keep checking for Ed-e. If he doesn't show up in a week I would say you are defiantly glitched.
But waiting did work for me.
