World Editor doesn't save hero attributes

Whenever I change a hero’s attributes (strength, agility, intelligence) and I save my map, and exit,
All the hero’s return to the default attributes if I load my map again.

The box ‘‘use default attributes’’ is actually checked when I restart.
Just tested it again and it happens every time.

You should expand and do riggerous testing, this is a serious issue if true. i asked a friend to test and they reported no such issue on saving a map while a preplaced hero with changed attributes is present.
