Please don't add achievements to the game that don't have the correct detections for them to be unlocked. It's so painful to do something that's challenging, and then find it doesn't actually work and unlock properly (I'm not saying this particular achievement is challenging, but there are some difficult ones which I don't have faith in them unlocking when this simple one won't).
The caravans were the 22500 gold caravans, not the 15000 ones.
I had two workshops, but because the W Empire declared war on Battania, and my workshop was in a Battanian settlement at the time while I was mercenary for the W Empire - I lost it and got no gold at all for it (Terrible feature/functionality btw, especially since when the war ends, you return and the people running the workshop don't even acknowledge it was yours before the war)
