Mission 10 on ogre race is way to hard for me, the tower is rapid fire (on x2 speed) and also I killed the first boss and they send out there next boss, then I was really just done for.
There's a problem in upgrading the level 4 town hall to a level 5 because you can only make a monster lab if you have a level 5 town hall and when your upgrading the level 4 town hall the monster lab is not in the "unlock" list.
