I have perhaps a similar bug occurring. This is before I have enough characters to have a reserve, so it might be different.
When I move character locations around during deployment, sometimes a face gets duplicated, so that someone's image shows up twice. If I hover the cursor over where the person-is-not-but-picture-is, it treats it (rightly) like no one is there. On my recent try, Madeline's portrait vanished completely while I have two copies of Emma and Sabrina showing up (see screenshot).
