for the uptenth time, there is no such thing as coal ingots!!!
there was a bug when there was colored npc armor that when you smelted it you got the color of the armor on the ingots. there was a luna house on lake superior a few years back that had over 30 different shades of ingots, its just that the shadow colored types were the most common to be smelted. kinda like the colored leather bug that was more recent.
there was a unstacking bug on ore as well, that when you removed one from a stack it was labeled ore instead of shadow ore. that ore can be locked down and is not newbiefied like the real coal is.
Yanaki...YOU ARE A MORON
dont talk about stuff that was OBVIOUSLY before your time...you just show your ignorance
coal ingots were WELL before the miscolored ingot bug...they were before multiple types of ore (verite/valorite and the rest) even existed
coal ingots were SIMPLE...they were a blackish hue...much like shadow ingots but considerably darker
i will admit i do not know thier origin...but to reproduce them was SIMPLE....all you did was take a normal stack of iron ore double click it, target the (coal ore) also called iron ore in game...and boom, all that regular colored ore is now mixed in with the stack of dark and it is now dark itself
at one time i must have had 100k "coal ore"...but did not know they were gonna be taken out so sold them beforehand for very cheap
so plz Yanaki, dont speak about stuff you dont know about...keep in mind they were taken out within year 1? or maybe 2 at the most....hard to remember
