Patch 1.05 notes state that wizard and cipher's base endurance has been raised from 30 to 36, and per level from 10 to 12. 
After patch i dismissed and re-added to the party lvl4 Aloth and his endurance was raised from 60 to 72[=36+3*12], which is correct.  
Newly hired lvl4 Grieving Mother has correct endurance 77[=(36+3*12)*1.06] as she has CON 12. 
But my lvl4 cipher protagonist with CON 10 still has only 60 endurance and after level-up he gains only 10 more, not 12. 
As i can't dismiss and re-added main character I don't know how to fix it.
