Lately my companions have been turning invisible. I can see where they are because of the BLIND health bar, but they do not follow me. I think it happens after they become unconscious. Anyone know of any solutions?

The companions don’t speak and I can pass straight through them.

They must be disabled. BLIND adds health bars over all NPCs, disabled or not. I'm not sure what mod could cause this to be honest.

Try disabling any plugins you have recently added related to companions, or something relating to NPC unconsciousness.

(When a NPC is disabled they are not rendered and they do not process their AI - including dialogue)

Hey, Thanks. I got my companions back through - prid <ref> -> enable

Awesome! Glad you figured it out
