GMS Unleashed - bugs and problems

I honestly don't remember. Have had this guy for awhile. I'm fairly sure that I didn't, though.
Won't allow me to add any points to the Blade Specialist skills, though it did let me add a point into a previous "job" (Fatal Blow), which I did just to see if it'd work.

If it helps, I have everything maxed except 6 Bandit Slash. However, I received 4 extra SP from that one time they reset everyone's SP due to an exploit even though I never used NX books.

It should be everything except minimum on Bandit Slash and Fatal Blow. Slash Storm, Flying Assaulter, Shadow Meld, and Mirror Image all max at 20 & require mastery books to do so. If you're afraid of adding too much SP into lower skills, just add an SP and see if you can add the higher skill or not. Repeat if necessary.
