That module was @Dancing Hoskuld experiment - he didn't want huts, workshops and factories to obsolete.Thank you! I'm beginning to not like Modular stuff for Regular buildings. We need to Integrate it into the RegularBuilding xml file and get rid of these Module files. This one you listed is imho not necessary at all. Sorry to say that DH but it's how I see it.
I had not looked at the SVN yet this morning.
What is the reason for Pottery to be in this module? What special condition was added that made it necessary to make a Module?
Instead those buildings can coexist - workshop requires 2 huts and factory requires 2 workshops.
There are beads, toys and few other resource producers with similar structure.
This module is going to be obsoleted by @Thunderbrd way or something like that.
