At least on the PS4 system, you stop gaining points from leveling at level 46. I am wondering if this was intended in the game design or a bug.
In total (without including skill point alters), a player can have 45 skill points, 16 attribute pts, and 12 talent pts at lvl 46. What's interesting is that an "!" appears next to ATTRIBUTES AND TALENTS when leveling up past 46.
