I had Cicero as a follower and ended up thrown in jail in Solitude. When I got out he caught up with me in Whiterun, but was limping like he'd been in battle. I healed him and he's unhurt now, but still limping around. I dismissed him to go back home and he crawled away.
Holy cripes I feel guilty.
Anyone had this happen? Does the NPC eventually walk normally, or have I crippled him forever?
