Kilill: I am in Prague running through Josef's Tunnels. I have two companions, Wilhem and Serena. Wilhem follows me and (mostly) attacks the same enemy I am. Serena just stands still. I can switch to her and take control of her, but the moment I change back to Christof or Wilhem, she just stops and stands still, even if someone is attacking her. I have exited the game and reloaded my save, and she still simply stands around when not directly controlled.

Is there some way to fix her behavior, or am I stuck trying to dig up an older save from before the glitch?

Kilill: I've checked out her AI settings. It does not seem to be her being on defensive mode that is preventing her from following me, as she stays still even on the neutral or aggressive stance.

Javokis: Sometimes party members will join you, but not be in the "group." Have you tried hitting the regroup button? Also check below their portrait to see if the group "light" is on. If not, try clicking it. I think pressing g or shift+g will toggle the grouping system.
