So suddenly the trading post caught fire. My villagers just seem to let the building burn.
Than the smokehouse across the cobbled road also catches fire. Everyone runs to the nearby wells and puts out the smokehouse fire.
The burning smokehouse is saved and life continues.
Meanwhile the trading post with all the gold and goods gets destroyed. all the gold and the goods apparently went up in flames.
Not sure what is going on here, but it seems like a bug with different categories of buildings, since all previous fires where extinguished as intended.
