Companion (The Elder Scrolls 5: Skyrim)

The one who was with you before always goes next to you or is in the place where you ordered him to stay, though not always, but for 2 days. Wait 2 in-game days and in theory you will part ways with your old companion.

In this case, this is another damned bug and unfortunately I can’t help here.

Look for console commands in the mighty spaces of the Internet, maybe there is one that unties the dragonborn satellite.

There was such a joke, I found a dog in the mountains and took her as a companion, and then she disappeared somewhere, so I couldn’t hire anyone else after that.

I had such a case, I could not take a companion. It turned out that in some kind of quest, a quest character was waiting for me. I completed this quest - everything became normal.

there is a console command. Search the Internet. I don't remember, but something like setfollowerscount to 0

In the console, enter set playerfollowercount to 0, then talk to the desired companion.

I had the same. So your satellite is stuck somewhere (cause of a glitch in the game). You have to start a new game just like that.

You don’t have to start, you need to take a couple of quests from associates and go through them because there will be quests with companions after these quests, you can take anyone.
