It's actually a bug report in the wrong thread but ok, I lowered thee width.
Admit it, you just returned two Duplicates a turn with Ambassador to trick us here.
I can try to reproduce it sometime, but that's not what happened. Also, there are two bots.
It looks like when you call a Duplicate after a Duplicate, it splits the timeline and the original timeline doesn't know that you called the second Duplicate yet. I think that's what happened. I could try to call more than 10 sometime, but I don't know if the bots will wait that long unless I add Counterfeit to the kingdom just so they waste time being stupid.
