Yeah, I encountered a bug where an assassin named byrd wound up making it impossible for me to use my psy fighter I got who was also named byrd. They both showed up when I cleared the team lineup, but when I put one in, the other vanished, and it was always the assassin one that got used.
Whoops; the game is supposed to check for names already in use and cull them from the table. Sorry about that!
no worries, just thought you should know about it.
