you need to wait for a poet to say a poem in a tavern on their own, them being in your company will probably be overwritten by a follow command that keeps refreshing,
so basically you need to wait for others to perform to learn anything new, or you luck out and find a book on a performance in a library?
ONLY IN A TAVERN? I've been wasting my time then. Even didn't sleep through one night. So this human poet from this human village needs to be in a tavern and
NOT AS MY FOLLOWER? OMG!
So, there is a tavern in one out of two dwarven fortresses, but they have no artists of any kind and no tavern keeper. They have mugs but no cups. Music instruments, which none music form I know uses. Some alcohol magically refilling in barrels from thin air and no tavern keeper of any kind. I rather doubt this human poet will go there on his own.
So basically, I need to make him hearth person and artistic follower. Then drag him to my crazy lagy with animals camp, build tavern, assign him to tavern and release from companion agreement and... he will stay in tavern performing? Or will he leave for his own village. Also, I will need to get him some LARGE armor, because large cloths are rotting completely out of my followers bodies in 20 days... If only trolls were using armor, this could be so... easy, but it just bites. I guess time to haggle some human soldier out of his metal armor. Armories in human main halls do not have enough of either lather or metal type of armors.
Also... I have seen villagers and fortresses refreshing their items in their armories and on their people. However for more then 1 month there is no refresh of any of those. I would like to know, what triggers inventory refreshes in fortresses and on peoples. At first 2-3 few weeks those were happening almost constantly. Now for over last entire month it did not happen even once. Only thing still switching from time to time is layout for sleeping rooms/workshops layer inside 2 dwarven fortresses. Did I break something with mechanics? All I did was to leave here and there some items or chests with items on floor, traded few bone rigs for this and that, or put some useless combat equipment into their armories. Any advice what to do to restart those refreshes again?
