Insulation option gone???

[ladyomni]

The option to insulate with daub with a hammer tool is gone... I just made all this daub and I can't use it? I want to get my homes insulated before winter to cut down on firewood use... is there a new tool or skill I need?

Have you got the perk for it?
Idk when you last played, but sinse along time now you have needed the perk.

Do you have the Hnadyman upgrade?
Open your hammer and use the upgrade option at the top
With this option selected, any building that can be upgraded will appear in a teal color; approaching the walls of the building will display the materials that are needed to perform the upgrade.
Upgrading a wattle wall requires daub.
Stone walls requires Limestone.
