they are NOT on different snappoints... they´re on the exact same one, hence why it works on the other corners perfectly except 1 single direction.
Instead of defending this game or the devs blindly and telling me i do it wrong, you should try it yourself!!!!!!
The pillars are allways on the inner side of stone walls and you CAN´T turn them outside if you only got a single square!!!! That´s the reason why i posted both methods..... it´s allways the same direction that gets mirrored and if i turn the foundation around the side that gets mirrored turns around too.
And the fourth picture is NOT how it´s ment to be.... take a closer look. picture 2+3 are the ones how it´s ment to be!!!!
This is a bug and everyone who tried to build good looking stone buildings knows about it.
It just didn´t get posted here yet since most people don´t even know about this "official" forum!
