Not sure if this is a CIT or Sentinel bug, so poking in both places.
I have a side-swapped mastermind, who was previously tracked. When I look at her page, aside from the fact she's still showing up as a villain, her supergroup is still showing up as her old vg, not her new sg. Even deleting the character didn't help, as it was just recreated with exactly the same sg as before by Sentinel.
