Hero points broken since patch

Since the 1.8.1 patch, my hero points on one character only are broken. The screen shows -24/35 at the bottom. I’ve gained a few points, and that doesn’t reset it to the proper values. (I believe it showed something like -26/33 right after the patch. It is not a display error only, as I can’t spend new points when I get them. Nor does uploading or downloading the characters from the server help. My other two characters are fine. Any ideas?

EDIT: respec does fix the problem…sort of. The points went back to normal except I lost a large number of em. i reset it when it said something like above, and ended up with only 37 points to spend - something like half of what I had previously on this character. Not too thrilled about that.
