How to lower Mi-Go Spawn Tower generation?

Is it possible to lower Mi-Go tower spawn rates? I’m playing Innawoods and really frustrated with >50% of the map being unavailable in random patches due to the density of Mi-Go towers everywhere. Is there a config or similar file that has some values that I could decrease? I would also appreciate any info on doing the same to fungal patches and Triffids.

How common these map features are is decided here: Cataclysm-DDA/specials.json at 456bf805f836a80597d43883ef0e9d3657ba4d54 · CleverRaven/Cataclysm-DDA · GitHub
Documentation on how to alter these values can be found here: Cataclysm-DDA/OVERMAP.md at 6726137b170968d49319f0949f569f156be7a5b8 · CleverRaven/Cataclysm-DDA · GitHub
You probably want to look at editing occurrences. Note that some specials have the UNIQUE flag which alter how occurrences works; see the documentation.

Thanks, this was super useful!
