Not sure if you want this here, it's about upgrading a barbarian metalworks to axefactory:
When I did this, my master blacksmith in the metalworks went to the warehouse, but
a newbie blacksmith came back when the axefactory was finished and my master blacksmith stayed unimployed.
No other relevant buildings were erected or upgraded during this.
