@MaiseNow Thanks. But I wonder if this is the same bug... In my case, the creatures come and go just too fast. They appear on the map and don't stay too long for me to do anything with them (hunt, attack, trap, etc.). I have even tried targeting them as soon as they appear, but, no help...
I am almost certain I have that DFHack on automatic, but I admit I might be "misremembering". Perhaps running the script automatically IS the problem? Perhaps all the creatures in my map are getting stuck and DFHack is getting rid of the creatures all too zealously? I'll have to chek. This is annoying. I really don't want to start a new world...

Leonardodiasm, that is a known bug in the game, which is why there is a script available in DFHack to "fix" stuck wildlife. It can even be set to run periodically so you don't get creature waves blocked by ravens suspended in midair, motionless, for eternity!

@leonardodiasm This mod shouldn't affect the rate at which creatures leave the map, unless the devs made some stealth-change to how frequency works. If you're seeing unusual behavior to that effect, it'd have to be something else causing it.

If you have DFHack there could be a script enable called "fixed-wildlife" or similar, it makes it so animals that get stuck get "evaporated into air" so new wildlife can spawn, or it could be another mod.

I really like the mod. I don't know if it is just me though, but the creatures don't stay around for too long? Not enough for my hunters reach the creatures, or they sticking around the fort to get cage trapped. It seems they are replaced by other creatures too fast, and not enough for me to plan what to do with them.
If it is just me or maybe it is another mod (I have quite a lot), I apologize. I am still relatively new to the game (300 hours). If you find out that it checks, I would like to leave a suggestion for the animals to stay around for a bit more time.
BTW, thank you for this mod and your other mods too.

yeah mb the rest where from the better spiders mod

@Nactarune The first one is me forgetting to replace ROCSKILLBUFF with BALANCEFREQ (I originally made this mod out of the skeleton of Skilled Animals & Megabeasts), so I'll put out an update to fix that. I can't replicate the other errors though, so they're probably related to another mod.

Getting these errors in the error log:

@eqN Yes, it would make them more rare since the creatures they'd be competing with for a chance to appear would have a higher frequency and thus be more likely to appear instead of them. This assumes though that the rare creatures in question succeeded their frequency-based chance to exist in both the biome and area of the biome in question, since if they fail that chance the chance of them appearing is 0% in that location either way. This "chance to exist" itself wouldn't be affected by this mod unless the creature has the large_predator token, since there is a hardcoded cap to the number of large_predator creatures that can exist in a biome and the slots are randomly filled with weighting based on frequency.

Absolutely love these mods! Say I use another mod that adds species with more typical frequency values. Does this mod effectively make those animals even more rare? The mod in particular I'm curious about is McNuggy's Mythical Beasts.

Part of me likes the idea of keeping those creatures 'Mythical' in appearance frequently, but I'm also worried they may become a bit too rare with the relative frequencies using this and your other Biodiversity mods.
