Made another patch update:
This one lets you use standard traps or pressure plates in place of machine inputs. Warning: machines will still suck in your gnomes if they are active, even if the trap itself does not activate. However, this should make weaponizing the machines easier.
The druidic system has been given many tweaks. Animals must be able to path to the nature shrine to be tamed, the 'tame all animals' reaction now only requires one druidic token (the former version used 10 because it was a carry-over from when you would automatically tame them regardless of merit; the new version takes merit into account but not distance or trainer skill), talking to birds now has unlimited range but must be done outside.
Animal training (at the Advanced Animal Training Area) has been tweaked significantly, it should now be more interesting to work with, as trainer skill and the nature of the animal have a lot more impact on training success, so you'll want to have a dedicated druid for handling your more stubborn animals. And since you'll want to keep track of which animals are trained to do what (for example, which one is the leader of an animal squad), you can now nickname your pets as well.
Most of these changes are in the .lua scripts, so they don't require a new worldgen. However, you will need to change the number of tokens required for the tame all animals reaction, and the nicknaming pets requires a new worldgen.
