The pathfinding in this game is horrendous. Don't put spiral stairs in your game if in testing you didn't find out NPCs can't even get down them right. This needs fixing. Stick it in my xmas stocking. Thanks.

Simple fix, tell your companion to go to home and never follow you again they svck anyways.

The only use I have for followers is a certain Daedric shrine.

Absolutely. Until a mod is released much akin to Oblivion's, where they teleport directly behind you whenever they get stuck (so you don't see them do it and ruin immersion or whatever) I'll be leaving them at home.
