I had the funniest glitch today. I was replaying Citadel, and I took Kaidan with me to the Casino.
I was talking with a man on the dance floor and Kaidan started dancing like shepard does behind us, nothing wrong there. I left the dance floor and I realized that Kaidan wasn't following me, he kept dancing at the very same place. Well, I left him there having fun,but I had a mission to do, so I headed downstair and, all of a sudden, he started moving, towards me, but his dancing animation didn't stop!! He wasn't walking at all, it seemed like he had wheels or something (or maybe he was using his biotics). He kept dancing behind me wherever I went
Sadly, It stopped when I reached one of the terminal I had to hack and Brooks started to talk, but it was hilarious while it lasted.
