Bronze disappearing

If anyone could give me some help would be great. My bronze is going missing and cant figure it out. I havent sent out any spies to use the bronze but it keeps disappearing. Any help with why its happening would be greatly appreciated.

Are you recruiting Vikings? They cost bronze to make.

Yes, reached out the the person next to me on the map and asked them,Cause it was driving me crazy lol. Didnt realize some of them needed bronze to recruit. Thank you for answering my question😊
