A couple of quick, but important, bug fixes in tonight's build.
Fixed a bug that caused the "days" to fail to advance as time passed in the game. This was also affecting coal since if the day was never increasing, the coal system was never kicking in. It will start to work properly once four days have past since this fix.
I redid the system that tracks what ore you are eligible to unlock. The old system was prone to errors, such as sometimes not giving you the quest to upgrade ore or giving it to you, but then not increasing the ore after you completed the quest. So I did a quick re-write and it is much more stable now.
Also making some good progress on the skills system and have about 10 skills planned so far. Focusing on passive buffs and specials rather than stuff that would require lots of F-keys. The system is more about tailoring your character a bit without becoming overwhelming.
When I say "buffs" though don't take that as just number increases. Some have special effects, such as the "Second Wind" skill that gives you a chance to not die when reduced to zero hit points and the "Killing Blow" skill which has a chance to immediately recharge your power attack if you kill a monster using a power attack.
I'll post an update about the skill system soon.
