The combat bug is most likely unrelated to this mod, it would seem one of your characters has a 'b_power_pot' effect active, since there is no such effect in 0.6.1c it causes a cascade of errors which can break pretty much anything. I would assume the issue here is imported save, import didn't remove all effects. Did you try to play on a new save?
As for the second thing, its a vanilla bug, its been there for a while now.
