Thank you for the high praise and the detailed comment! I always enjoy reading those :) Glad you've enjoyed what the game has to offer so far! I hope you'll like the new updates as well
The building materials snafu is entirely my fault, I completely forgot to adjust its drop rates after implementing the guild upgrades. Will do that in v0.1.9. Since I'm the only person working on this and the scope of the game keeps expanding, little things tend to slip away :)
