small thing I noticed that seemed to be a bit of a bug
to promote a blacksmith to an engineer you need a blacksmith of level 2 and an engineer’s Wrench…
however you need to be level 3 to make the wrench.
the herbalst/ cleric
the potter/masion or the mason/potter ( depending on what faction you choose)
both need level 2 and you can craft the item by that crafter at level 2
not sure if this would need to be adjusted
