For Homeworld 2, Fleet Command was voiced by Jennifer Graveness, causing fans to protest who wanted the original voice of Karan Sjet in the second game as well. The change sparked long-running speculation during the ensuing years, without any clear answer. During presentations of the Remastered game editions at PAX South, it was stated that at the time voice acting sessions were being conducted for the second Homeworld game, Heidi was nine months pregnant and as a result her voice had changed, preventing her from being able to perform the role at that time (this is not unheard of, as the same issue arose for Kristen Bell who was similarly pregnant during recording of dialogue for the animated film Frozen).
