stat point gain didn't occur
 

I've been making use of the higher difficulty setting after killing draaien, and when i leveled up i didn't gain stat points.

That's strange. What level did you not get points for? Did you not get attribute or skill points?

level 63, and attribute points. skill point gain was fine.

Ok, I'll look at it.

Other information which may or may not be important:

I'm using the max party mod, the challenge mod, and some quest system modifications. this is the first time i've leveled up on a difficulty setting above my character level. I have some XP debt. most of the rest of my party is level 75-78 or so. my character is a warrior. I'll see if my recruits get the attribute point gain when they level up.

I just occurred to me what might be going on. In one of the last patches I added a AttributePointsPerLevel in systems.gdb (that is set to 5). If one of the mods you are using is overriding all of systems.gdb than it is probably not grabbing the correct value.
