Currently playing Minecraft 1.12.2 Totemic version 1.12.2-0.11.6.

In Line 21 of the totemic.cfg config file I set:
B:enableVillageTipi=false

Then went into both an existing world and generated new chunks, and a new world as well. Found a Village in both that still contained a Tipi. It seems that the above setting has no effect on the Tipi generation in Villages.

(Obviously I closed the game before applying the config. In fact I restarted the game multiple times since then, and Tipis still generate.)

Edit: Accidentally copied the wrong line from config to the title of this bug report, but I fixed it now.

Turns out I had a space after false. Deleting it resolved the issue.
