I only know of Sailor Cat’s mod, but wasn’t sure if it was hotseat/PBC compatible.
Does anyone know if it is if everyone has it installed, or if there is a mod that will work with hotset/PBC?
The sailorcat one is not PBC compatible because the author marked it as a UI mod. This means it is not forced to be on by each player and a player that loads without the mod will not have the same hut restriction settings as the host. Note that hut locations would be the same as those are determined on map generation.
Calcifer made a PBC compatible version. You can find it in his dropbox here:
