So, there's no area around my base where the quarry will successfully place due to it being so large... I moved to another island, systematically cleared the area and it still won't place. My starting base in my solo game is in the river area on the islands due to sheer convenience...

So, I build a large circular foundation to flatten the ground - it still won't place the quarry. What am I doing wrong? I got the lumber mill to place correctly and it works, I haven't attempted the iron works but what I could use at the moment for further expansion is stone which is becoming tedious to gather and I have an overabundance of food so I figured I'd try the mod...

But I can't get the one building I actually needed from it to place anywhere.
