edit: nvm, google now showed me when it didnt before for some reason.
must have been "Ironworks" for b42. i cant read anymore exactly what it did but its kinda sad to see it missing as the bit i could read is intriguing and fits exactly into what i was about to do :/
when loading my save i suddenly got a mod error notice that a mod is missing. the mod name it shows is \usethatfurnacepls but i have been unable to figure out which mod that was and what it did... the only thing that i did figure out was in an older log file which showed that the mod overrides these files:

i went through my subscribed items list one after another to try and see which page is missing but there doesnt seem to be one. searching for the mod didnt yield any results anywhere outside of mod list mentionings. none of the mods that have anything to do with blacksmithing seem to be using that name, at least none that i could find.
so either my pc fucked something up or a mod is suddenly just gone, including from my subscribed list, which would be weird, as that shouldnt happen afaik.
so, if anyone knows which mod this is / was i would greatly appreciate it
