Makes perfect sense; it should probably be reported at larian.com forums. I would think that a bug like that would be widely reported though, unless it’s specific to your hardware somehow.
I also seem to remember reading something about not being able to apply points in the mirror to the lone wolf maximum if you took that talent, you had to just assign to the max, then exit the mirror and you could apply the rest so it sounds like they’ve got a few things to work out with the mirror.
