Lol, that is true, you did get my attention. Sorry about that. Managing development of the game and attention to peoples concern is difficult with so many issues that need to be addressed. Not trying to ignore anyone.
Ya the mark up is pretty low. I am tweeking the numbers to get it just right. I have to consider how much Charisma will affect the end price as the player levels it up. In the end, if I increase the mark up then I have to increase the prices for everything else so they are still challenging to obtain while taking into account charisma. Balancing act.
The copper dagger is probably bugged and ill look into the possibilities to why there is no profit.
Ya you can totally use a greathammer head with the one hand grip and sell it as a one hand hammer. In the end, it is a one hand hammer just with a really big hammer head.. So you'll get more for what you would normally sell a regular hammer head. The idea is you can make any weapon and sell it based on what the customer requested even if its non conventional. Still working on it though. Its definitely not where I want it.
