The steps:
- Have one zombie enter the field and be killed.
- Use Raise Zombie to bring them back, get the +6/+6 bonus.
- Have them killed off.
- Have a second zombie of the same type enter the field.
- Use Raise Zombie.
Result - The zombie is brought back, but the bonus is apparently applied to a card that does not exist on the battlefield instead of applying it to the reinforced zombie.
While the zombie IS reinforced, they should still get the bonus, should they not?
