Starting 3 mission with a reseted hero to level one

[Balancer]

As the topic says . I playied the game with necro as the first choice all goes according to plan and i want to restart the third map/mission to focus only on the demons.

while the autosave works ok (gives me me my level 16 anastasia) if i restart the mission or i start the map from the campain map i start with a level 1 version of her. No rep no items no nothing.

Any ideas how i can correct this? I thought about replaying mission 2 but what happens it doesnt correct the error ?

Thanks in advance for any help
