Effectively at the beginning in our guild, we collected tons of clay, water and fiber for our builder to build a Furnace every time it broke, that raised his skill (and our blacksmith as well). Then destroying those Furnaces our Leader can raise his Authority necessary to evolve the Guild Monument. It is a matter of adapting and always looking for ways to benefit from adversity.
Particularly in my Guild we plan for the future, we settled first precariously near a clay source with nearby iron mines and once our builder could repair, we moved to our final settlement.
Learning to repair is the challenge of a builder, some of us like a bit of difficulty in this game, having everything so easy for me would be boring.
Go in peace.
In a game in BETA version we have to cope with the stressed development team with black humor
