| Summary | 0004505: Smaller than expected underground vermin populations |
| Description | Underground vermin like cave lobsters, cave fish and purring maggots have much lower population numbers (as shown via "export map/gen info" from Legends mode) than surface vermin with similar POPULATION_NUMBER tags. This means that most underground lakes will have no fish or lobster in them, and there are only very few purring maggots to catch. |

I did some tests, examining populations in memory both for subregions and feature layers during a paused worldgen, and while surface populations are mostly within the expected ranges (POPULATION_NUMBER range multiplied by the number of region tiles), feature populations were indeed vastly lower - a cavern covering 29 region tiles contained only 390 naked mole dogs and 351 elk birds compared to the 435-870 and 725-1450 I would have expected. As worldgen goes on, those numbers only seem to get smaller. |

Still present in 0.40.04. As an example, purring maggots have the same POPULATION_NUMBER stats as large roaches. In a pocket world there were 25 times as many roaches as maggots, and in a medium world 5.3 times as many.
*EDIT*: Also, the pocket world was 250 old, but the medium world was only 5 years old, so as noted in the previous comment, the disparity might grow the further worldgen goes on.

Something in 0.40.05 has made the problem go the opposite way, so that there seems to be too *many* underground vermin. A 250 year old pocket world had 5 times as many purring maggots as large roaches, while a 5 year old medium world had 14 times as many.
Anyway, *THIS* bug has definitely been fixed. |
