Hey everyone, been playing for the past 3 or 4 years, just now had a reason to register on the forums, lol. So I decided I wanted to experiment with a strictly-contained fort, in that nothing could get in or out unless I wanted it to. This was both to keep sieges and migrants out, the latter because I always have more dwarves than I'm ready for after the first wave or two, and I'm a terrible macro-manager.
To kill off any undesired creatures loitering around outside waiting for entrance, I chose to embark on the tundras. All was (and still is) going well. It seems that there are either no goblin civs this far north, or it's too cold for them up here, as I've not had any sieges in the nearly 3 years the fort has been running. The first wave of migrants was forced to freeze, but I let the second wave come in. A dwarven caravan came and left, though no exchange of goods occurred.
So here's my actual question. An elven caravan came by, stayed a while, and then when it said they were about to leave, they never did. I assume this is because I never let the liaison in to speak with my broker. Eventually, either due to dehydration, cold, hunger, or boredom, the elf trader went berserk. The frame after that, his camel became melancholy and began dumping his goods all over the ground, including many barrels of golden salve and some exotic caged animals I'm interested in. I assume he will not pick his stuff back up, because that doesn't seem like something the trader NPCs are programmed to do, meaning he will eventually die and I can go and take his stuff.
Will more elven caravans come? Are there any repercussions? Is this common? I personally found it hilarious.
