Might as well be a bug. With the anti macro code off the current system of stat gain just doesn't work. Its going to be the same problem as on Hybrid only a lot worse. Your characters will max out their skills long before they come half way to maxing out their skills (some skills, like blacksmithing or mining might be exceptions).
What you'll have to end up doing is lowering one of your gm skills to raise another just for the stat gains.
My advice would be to speed up the stat gains somehow. Hell, I have one character nearly 7x GM and I don't think he has a single stat above 50.
Until then, my advice is this, GM the following skills just for the Stat gains. then lower them:
Strength: Arms Lore
Intelligence: Spirit Speak
Dex: Hiding or Music.
