You have to kill the level 10 Boss before you receive the achievement for it. So if it says level 10 on the Boss Battle page then that is the next boss level - not the one that you beat. If you still feel as though you are missing skill points then send a message into support and we can look into your account.
it whas The Great Wall Zombie (Level 10 China Single Boss) i kill next time it is lvl 11 but has stille not gote my 12pts rewards in stats and i has lvl up after it but nvm. it is same on all fb games then it is bug the company who makes it always say it is players fault.
Can you send in a message to support with all of your information so that we can look into your account to see what happened to the points?
