It's me again. I suppose, you will see my questions here quite often. Because I can't find out a lot of things myself.
Btw, previous problems with trade licenses got solved as soon, as I began new fortress. I also have regional rain now, but it looks bugged again. In Joyous Wilds biome I have only dwarf blood rains.
1. How much sovereigns/shillings I will get for X shillings/coppers respectively.
2. What the luck song in the tavern does? Which aspects of the fortress it affects?
3. Where can I create musical instruments like harmonica, triangle and others? Where can I make sawblades?
4. Is it possible to choose type of large gem, that is created in gemcutter's workshop? I'd like to produce large diamonds to sell it to fine goods store.
That's all for now. I hope, you won't be annoyed by few more stupid questions in nearest future. I try to search for answers on wiki and in built-in manual first, but still can't find it. Prob I just miss them because of my english.
