The stat distribution of (5,3,2,4) you are getting is due to leftover values from you messing with the customized stats. Normally it would reset to (4,4,4,4) when the player reaches certain sections of the customization. Though the player character is part of the Mages Order, he/she is not required to adhere to a specific play style nor be good at magic.
Quickstart appears to be neglected because almost nobody seems to use it and care about the results. Even I noticed the missing stat points(normally 2), but haven't bothered fixing it cause it didn't matter for testing, which is what I use quickstart for.
Currently, the player does not use racial stat distribution, so race has no effect. Would you prefer that quickstart use race as a base for the stats? Would you add stats to reach the normal 18 for a player? Would you evenly or randomly distribute these extra stats?
