No, companions should not lose their inventory when dismissed. Damned. I did the same with Cait. After I got them, I stuffed them with junk and recruited Strong.
If you dismiss companions in Fort Joy, they will return to their original location where you first recruited them.
First, yes, you can retrieve it later. When you dismiss a follower, they will return to their home location – by default, this is usually where you first hired them. You can re-hire them there by speaking to them again and asking them to join you for another fancy adventure.
They go to their “home” or the Lucky 38 (if you’ve already been there). You can always recruit them again by speaking.
Companions’ default armor does not decrease, and their default weapons do not run out of ammo. If you give them another weapon, you must give them ammo for it.
Cass in Mojave Outpost, ede in primm, Raul in Black Mountain, Boone in Novac, Rex in Freeside, Veronica in 188 Trading Post, Arcade Gannon in der alten Mormonenfestung und Lily in Jacobstown .
Where do dismissed followers go? When you dismiss a companion in Fort Joy, they return to the area where you originally met them. To recruit them again, make sure you have an empty spot in your party for another member and return to where you met the dismissed companion to recruit them again.
After completing the quest, Arcade will no longer be a constant companion and will return to the Mormon Fort (on the Legion/NCR side) or the Lucky 38 (on the NCR side).
Sometimes ED-E on close will not appear as directed in Primm or Lucky 38, effectively disappearing from the game. For unknown reasons, ED-E does not levitate while other Eyebots do, what causes this is unknown and no fix yet.
Probably the Sanctum. When you “dismiss” a companion, you will generally be asked where to go. If you can’t find dog meat where you sent him, build a kennel, go and come back, he will be in the kennel.
Strong never goes into stealth mode. If Strong is dismissed without naming a settlement, he will be returned to the Trinity Tower Lobby Level. Strong prefers melee weapons like the super sled or rifles.
In the DLC you can take your companions with you.
You can’t take companions with you, but there are 2 companions you can travel with while you’re in the DLC (but you’re trapped there until it’s over, and you can’t take any of the Do side quests after it’s over).
In fact, every DLC apart from Old World Blues has sections in the main quests that require you to have a companion in one form or another, as well as many sections where you can bring a companion, but it’s not mandatory . You cannot do the DLCs with companions.
