Extensible Follower Framework, "train" command not working

[Sceadugengan]

Hi there!

 

Like the headline says, the "train" command isn't working for me.

I recruited a random NPC from an inn via the MCM recruit option and since then the stats of my follower hardly changed.

For example the HP: It stayed at 73 HP the whole time, even though I gave it the "train" command several times.

My character is already at 250+ HP and enemies at this level start to one-hit my follower...

 

Do you know something to fix this?
