I noticed that yesterday as well. Multiple times Walleye (a Knight) appeared to be in control of C30, attached to P29 which to my knowledge was never controlled by the Knights, and this would be unlikely due to P29's location.
Closing and re-opening the task group window at one point caused the ownership to update to a Bish player, so it would seem this is definitely just a display bug. I do know that other players were able to alter the course of the CV while I saw it as controlled by Walleye, so I don't think it's an actual issue with CV group control.
