Lost ninjas on 4.0 upgrade

I have noticed that I have lost my ninjas after the 4.0 upgrade.  

Was this a hiccup or did I loose them some other way?

Can you next time open a search first, before opening a new topic. Here 

There is already a topic. Today it will be fixed. Honestly, I don’t miss them, raiding without ninjas works much better, since they activate towers and make wolfs howl. 

Update: All the ninja rewards should be paid out by now, my bro got them on his account a few hours ago
