User blog comment:AgentG231/What specifically is the bug in the Animus 1.28 that made Altair can't swim?/@comment-5088097-20130425063948

There hasn't been any specific mention of what this bug was, as far as my memory and knowledge can extend to. Only the trivia section of Altair, makes a vague mention of it... and I'm estimating, that's where you learned it from. Sorry I couldn't assit you further.
