Okay, so I took the contract to kill an escaped convict from the Companions and had Aela as a follower. After getting owned by my target the first time around, I then found him again, wolfed out and batted him around to death like a kitten with a ball of yarn. After changing back into human form I noticed that Aela was no longer following me. I found her back in Jovasker (sp?). My question is:

Do you lose you follower(s) everytime you transform?
