I messed around a little with the liquids command and spawned a river source, which worked very nicely but it spewed out a LOT of critters and fish with it. I'm glad it makes it an "alive" river, but the amounts seemed like they were too high. However, I did spawn it on the side of a cliff and not in a realistic channeled region like a river would normally be in so I don't know if that somehow played a role in the creature spawning. What governs that? I'd like to use it at a embark location to add some spice to it, but the numbers of creatures (especially vermin types) was so high that it was getting heavily cluttered within just a few minutes of game time. If it kept up like that throughout the life of a real fort it would just get crazy. I also wondered if it was spawning multiple sources due to more than one tile being spawned, all classified as river sources.
I would also like some advice on what bug-fix type of commands I should run to help with FPS and other game problems. I'm aware of stable-temp and growth-bug and to run dead-units from time to time. I knew there were more, but I couldn't remember which ones and I never discovered if they should be ran every time you load your game.. So some clarification on this would be appreciated. Thanks!
