Autoheight always places building at sea level
autoheight always places building at sea level. But not all of them, just some. Not clear what triggers that.
auto height is a bad thing, if i were you i would specify height manually tbh
 

Not 100% sure but I think it has something to do with triangle foundations. I was having the same issue and noticed that if a base is all triangle foundations, it pastes at sea level. If there's even a single square foundation in the build it pastes normally. Not sure if that's all there is to it but just something I noticed earlier.

Well done man cheers, sorry for bringing up a stale thread but thats it. 

I had a few problem bases that Always (100%) spawned underground, went through everything in the file, dunno.. 
went and checked it now, yes it does have all triangle foundations. Add a twig square, resave, paste..

cheers again,
