Ok then here are the vicinity stuff ...
- Centipede = Silk AND Lobster
- Dragonfly = Silk AND Fish
- Junebug = Silk AND Indigo
- Dung Beetle = Silk AND Elephant
- Pillbug = Silk AND Shrimp
- Rice Bettle = Silk AND Rice
By having them as combo buildings means not every city will have them and thus make them more unique.
Anthill I thin should stay like the Termite mound and not give culture. Also like the termite mound it comes at Tool making and goes obsolete early at cooking.
Here are my tweaks ...
