I quit very soon.
Honestly, building Damascence swordsmith + Crossbows + Titanium smelters (i dont have these buildings and i dont thing i need them) worths more that buying from TO a SILO + WATERMILL and finish with it.
The only possible good thing from this buildings is that they MIGHT come handy in other quests... but meh...
BTW, i got granite in the first search too, and did the ML ls in the first day or something. But then quit.
