Sorry to open this issue here, but I'm kind of desperate. The issue is the following (my mother language is French)

I purchased a special pack today, this pack contained between others, 60000 units (warriors) that were injected in my city, and they consume so much food that I cant' decently keep a food stock.

I want to withdraw all those units... and after many researches... I couldn't find where I can get rid of them.

Could someone kindly help on this issue ?

Thanks in advance !
