I wanted to buy dagger because there was an offer for offensive ships and i gave 3040 rubins and no dagger gotten. Can you please have a look on it?

Did you check in your harbour?

Hi! Are you sure the rubies disappeared?

Sometimes it can happen that the purchase is interrupted by to a short break in the internet connection. In that case, after the connection resumes, there will be no purchased item or unit on your account, but the Rubies will also return.

I checked first in my depot, then in my harbour. I had before 27 dagger and that was the number, that i had after the purchase. After i did the purchase (there was much lag, but the rubies was gone (before more as 3000 and now was only 40). I bought a package rubies (8000 and bought again daggers and this purchase worked). But the first rubies are away and no daggers.

Go to that link above and raise it there. They'll sort it out for you.
