Unable to respect passive skill tree

As the title says. I am unable to respect my passives. When in the passive tree, I can refund skill points, and even re-assign them, but confirming the changes does not take my gold and only visually applies the changes.

The banner that shows the cost and to confirm does not go away, despite the animation for setting the new skills playing. Saving and quitting resets the changes back to before respecting.
