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.

 

 Can confirm this bug. If I load my 1.04 savegame with a full custom party, my main mage and my custom cypher both have the old endurance and health values. If I use party management to remove the custom cypher, then re-add it, it now has the new endurance and health, but my main mage still has the old endurance and health

Same...Aloth now l.5 has his endurance at 84 (36+12*4) and health at 336, while my main character (also a wizard l.5), with Con. 4 and a -18% penalty is still at endurance 58 and Health 187...which unless I'm calculating this wrong, it should be a quite a bit higher with the new specs (at least endurance at around 68 and health above 200)

 I found a solution that sucks. If you install IEMOD and use the ChangeClass command to remake your hero wizard as a new wizard it will then end up having the correct endurance and health. But it will lose all scribed spells. So then have to use the AddAbility command to re-add all lost spells.

Thank you for the info, Narla. I maybe should just try your solution.

It is even easier for the cipher without all those scribed spells.
